What are the orbits of the planets?

The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit).
  • What orbits Jupiter?

    The average distance between Jupiter and the Sun is 778 million km (about 5.2 times the average distance between Earth and the Sun, or 5.2 AU) and it completes an orbit every 11.86 years. The elliptical orbit of Jupiter is inclined 1.31° compared to Earth.
  • What are orbiting the sun?

    All of the planets are in a circular or elliptical orbit around the Sun. Our moon and the moons of the other planets are in orbit around their planets. Comets are in an irregular orbit around the Sun. Most asteroids in our solar systems are orbiting the Sun in a band between Mars and Jupiter.
  • Can Pluto ever collide with Neptune?

    According to NASA, they will never collide. This is due to Pluto's orbit being "above" Neptune's orbit. According to the same page the closest the planets ever come close to each other is 2 billion kilometres.

How long does it take for the planets to orbit the sun?

Earth takes 365 days to travel one complete orbit, while Mercury takes 88 days and Venus takes 224 days, so the time between alignments will require each planet to make a whole number of orbits around the sun and return to the pattern you see in the figure above.

Can the orbits of the planets change?

If the Sun and Earth were the only things in the solar system, our planet's orbit would be an ellipse of virtually constant shape and orientation in space. However, because the other planets pull on Earth, our orbit does change slightly over time, in orientation and in shape. Same for the other planets' orbits.
  • What is special about Earth?

    To enable life, this most special of attributes, planet Earth has a number of ideal features. It is unique among planets in our solar system for having water in its liquid form at the surface, in an amount conducive to life evolving.
  • How long is a day on the earth?

    This period of rotation is about 4 minutes less than 24 hours (23 hours 56 minutes and 4.1 seconds) and there are about 366.242 2 stellar days in one mean tropical year (one stellar day more than the number of solar days).
  • Is Earth a Roman god?

    In ancient Roman religion and myth, Tellus Mater or Terra Mater ("Mother Earth") is a goddess of the earth. Although Tellus and Terra are hardly distinguishable during the Imperial era, Tellus was the name of the original earth goddess in the religious practices of the Republic or earlier.
