A live view of the solar system and planetary positions today

This site brings you face to face with the solar system as it is now... and also how it was and how it will be.

NEW : Events Calendar - The Next Big Solar System Event will be:

Southern Delta Aquariids Meteor Shower

This yearly meteor shower occurs when the Earth moves through the debris of the breakup of the Marsden and Kracht Sungrazing comets. It usually peaks around July 28th/29th and can peak at 15-20 meteors per hour. LinkEnds:

Have you ever wondered "Where are the planets right now?"

Solar System Map of planetary positions

For people interested in astrology the current  positions and movements of the planets are very important and can give you a clue into how you are feeling and how your day is going to pan out. For astronomers, it's equally important to know where the planets are so that they can observe them. For others, getting an understanding of where the Earth is in relation to the Sun and moon and planets is just, well, sort of nice to know. If you've ever sat outside at night and got into an discussion about whether that bright star is actually a planet, and if it is - "Which planet is it?", then this site might help narrow down the options!

This online orrery (Note: an orrery is a machine that shows planetary positions) will hopefully help you to understand what's going on out there.

Our live Solar System Map - Getting Oriented

View of earth

If you have Adobe's Flash enabled on your computer, then the application shown above plots the position of the Earth and planets using data from this NASA's JPL website and is accurate between 3000BC and 3000AD. If you don't have flash enabled then we'll be showing you a simpler view of the solar system showing you the current planetary positions with the option of moving up to 30 days forwards or backwards.

Solar System Map of Current Planetary Positions

Both apps show a solar system map - a "plan view" of the planets laid out in the plane of the ecliptic (the flat plane in which all the main planets move about the Sun).

Dwarf planet positions are also shown - but it should be realised that these objects often rise far above and below the plane of the ecliptic. This is because their orbital planes are tilted with respect to the ecliptic - by more than 40 degrees in some cases. So be aware that just because the app may occasionally show a planet and a dwarf planet to be very close to each other in the plan view, they may, in fact, be separated by a large perpendicular distance.

Earth's Tilt

As you may know, the Earth's axis is tilted over by 23.4 degrees and the Earth's North Pole currently points at the star known as Polaris - the North Star. The app is arranged so that the view is fixed to the stars and that Polaris is always off the top of the screen (and not shown). This means that the Earth's north pole is (currently) pointing towards the top of the screen, and the south pole towards the bottom. During the summer months of the northern hemisphere the north pole is pointing more towards the Sun and so the Earth is (currently) shown below the Sun. During the summer months of the southern hemisphere, the south pole points towards the Sun and so the Earth is shown above the Sun.

Unlike other online orreries in which you can look at the solar system from all angles, this site always shows the same view to try and help you keep your orientation. A north/south control allows the view to be changed from looking "down" at the northern hemisphere to looking "down" (or is it "up"?) at the southern hemisphere. This allows you to tailor the view to the hemisphere you are in so that you can more easily relate the planetary positions as shown in this app with what you are seeing in the night sky. In both views the North Star is kept towards the top of the screen.

Yearly Clock - or 'Where is the Sun?'

Because the display is locked with north tilting upwards, it acts rather like a clock face in which one revolution of the Earth about the Sun is one year, and each of the constellations approximately map to months of the year with January being when the Sun is mostly in Capricorn and December when the Sun is mostly in Sagittarius, etc.

The Zodiac, Equinoxes and Solstices and the seasons

Solstices and Equinoxes

Winter (Northern Hemisphere) Solstice Summer (Nothern Hemisphere) Equinox
December Solstice March Equinox
Summer (Northern Hemisphere) Solstice Autumnal (Nothern Hemisphere) Equinox
June Solstice September Equinox

The Zodiac display is centred on the Earth and oriented with the tilt of the earth. This display shows in which sign of the zodiac the Sun lies at any time. The sign of the Sun at a persons birth is called that person's Star Sign.

The Zodiac is locked to the tilt of the earth in this way: Because the earth is tilted the Sun lies in the northern hemisphere for six months and then in the southern hemisphere for six months. When the Sun crosses from the northern to the southern hemisphere this is called the Vernal Equinox and this event defines the direction between Aries and Pisces and hence the orientation of the whole Zodiac for the following year.

Currently, the winter and summer solstices occur as the Sun crosses the vertical zodiac line and the spring and autumn equinoxes when the Sun crosses the horizontal zodiac line. So, to use our anti-clockwise clock analogy (e.g. with the app in northern hemisphere mode) the winter (December) solstice is when the Earth is exactly at 12 o'clock from the Sun, the spring (March or Vernal) equinox is when the Earth is at 9 o'clock from the Sun, Summer (June) Solstice - it's at 6 o'clock and autumn (September or Autumnal) Equinox - it's at 3 o'clock from the Sun.

The longest and shortest days occur at the Solstices. At the Equinoxes, the day is almost exactly the same (12 hours long) all over the world.

The Zodiac - and "Hey... That planet is in the wrong place!"

The zodiac in the flash app always shows which sign of the zodiac the Sun is in. However it may not be correctly showing which sign each planet is in. "How can that be?" you may ask. The reason is that the app has a slider control which changes the orbits of the planets from a diagrammatical view (i.e. all the planets in nice neat, equally separated, circular orbits) to a real view (i.e. all the planets in elliptical orbits with all the inner planets squashed in next to the Sun and the outer planets being widely spaced). Only when the orbit realism slider is in the real position (against the tick icon) are all the planets definitely shown in the correct sign of the zodiac. For info on the flash app controls, click here.

This page by default shows the diagrammatic view. The Astrology page by default shows a geocentric view in which all the planets are shown where they are relative to the Earth - but without distances. This makes it easier to see where they are in the sky, and also means they are always shown in the correct sign of the zodiac.

The Zodiac - and "Hey... That planet is not in the star constellation shown!"

Sometimes people look into the night sky and expect that a planet shown to be in the zodiac sign of say "Cancer" will be sitting over the star constellation Cancer. This is not always true since zodiac signs and constellations do not match up one to one. The reason for this is that for one the constellations vary in size whereas zodiacs are all the same and two the constellations have moved (or rather the direction the Earth's north pole points has changed) since astrology began.

Indeed the direction the north pole points changes by 1 degree every 72 years (it's called precession), and completes a whole circle about every 26,000 years. This means that although the stars (mainly) stay in the same place, the solstices and equinoxes (which are defined by the movement of the Sun with respect to the Earth's axis) change by 1 degree every 72 years with respect to the stars. And because the position of the zodiac is defined by the equinoxes, it also rotates by 1 degree every 72 years with respect to the starts.

Our flash app shows this precession in the zodiac. As time is wound forwards the Zodiac rotates in a clockwise direction (northern hemisphere view). The positions of the all planets (including the Earth) are shown with respect to the stars and so are unaffected by precession.

Which Planets are in Retrograde?

Planets in Retrograde

When the zodiac display is enabled, glowing indicators appear on those planets that are in retrograde - which means the planet is appearing to moving backwards from its normal motion when viewed from Earth. The image to the left shows Jupiter, Uranus and Neptune in retrograde because Earth is speeding past on the inside orbit.

In Astrology, it is very important to know when the planets are in retrograde, and also when they stop and start to move forwards again (called the Stationary Direct) because it is believed that this motion can reverse and enhance the effect of the planet. For Astronomy, retrograde motions have no importance since they are simply the result of the motions of the planets relative to Earth.

Future Developments

This software is still under development with additional features being added when we can. Please feel free to let us know if there are any features you would like added or questions about the solar system you would like answered, or give us any comments on the application.

Other Free Online Orreries and Solar System Simulations

For some reason 2 of the 3 online orreries I used to list here are no longer running which is a real shame.
Anyhow, until I find some more good online orreries out there here is a good one:
