Mercury's Orbit

Mercury's orbit is the most eccentric of the planets in our solar system. This planets orbit period is 87,969 Earth days. For every 2 orbits of Mercury around the sun, it rotates three times on its axis.

Venus's Orbit

Venus is the second planet from the sun. It orbits about every 225 Earth days. The orbit of Venus is the most circular in the entire Solar System. Venus orbits closer to the sun then Earth, so it takes less time to orbit the sun. Venus orbits the sun at an average distance of about 108 million km.

Earth's Orbit

The Earth's orbit around the sun is a speed of 108,000 km/h. The planet travels 940 million km during one orbit. The earth completes one orbit every 365 solar days. (that might help explain the need for a leap year) The earth is never the same distance from the sun from day to day.

Mar's Orbit

Mars is the fourth planet from the sun. The orbit of Mar's i the second most eccentric in the solar system. The average distance from Mars to the sun is 228 million km and takes 687 Earth days to complete an orbit. Because of Mar's axis tilt is similar to Earth's. Mars has seasons like Earths.

Jupiter's Orbit

Jupiter is the 5th planet from the sun and the largest planet in the solar system. The orbit of Jupiter, like that of all the planets is elliptical instead of circular. Jupiter is about 4.5 billion km in distance away from the sun. It takes about .67 earth years for Jupiter to complete its orbit.

Saturn's Orbit

Like all the planets in the solar system , the orbit of Saturn isn't a perfect circle. It follows an elliptical path around the sun. Since Saturn takes about 30 years to orbit around the sun its only been around the sun about 13 times sine Galileo observed Saturn in 1610. Saturn is the 6th planet from the sun and the second largest planet in the Solar system.

Uranus's Orbit

The orbit of Uranus takes 84 years to complete one revolution around the sun. Uranus also follows an elliptical path around the sun. Its orbit isn't circular like some of the other planets in the solar system. The saw Uranus is unique among the other planets in the solar system because of its axial tilt

Neptune's Orbit

Neptune is the farthest planet from the sun, the 8th planet. Neptune orbits the sun at an average distance of 4.8 billion km. Neptune also follows an elliptical path like some of the other planets in the solar system.

The Inner Planets

The four inner planets are very small compared to the four outer planets. They are solid and rocky planets with a very thin atmospheres. They have very few moons and Mercury and Venus have none. Earth has one and Mars has two small ones. The four inner planets are Mercury, Venus, Earth, and Mars.

The Outer Planets

When you look at the four outer planets you see that in a proper distance scale they are spaced out a lot more then the four inner planets. These planets are very large and they are almost entirely gas. They are nicknamed Gas Giants . They also have many moons. The four outer planets are Jupiter, Saturn, Uranus, and Neptune.

Galillean Moons

Galilean Moons were discovered by Galileo in 1610. They are the 4 largest moons orbiting Jupiter. This discovery showed the impotance of the telescope as a tool for astronomers. Helped disprove the idea that the Earth was the center of the Solar System. The sun was the center of the Solar System.

Comets, Meteors & Asteriods

Asteroids ~ A ring of asteroids lies beyond the orbit of Mars. Most asteroids are very small but a handful are quite large objects. When the solar system formed 5 billion years ago, leftover rocks and matter remained as this asteroid belt.

Comets ~ are also frequently found out here in deep space or their way toward or away from the sun. Their orbits can take dozens or even thousands of years to complete once. Comets are bits of rock and dust mixed with frozen compounds.

Meteors ~ are small rocks that are constantly shooting around in outer space. These objects are pulled in by gravity of planets and moons and streak through the objects atmosphere becoming a meteor and if it doesn't burn up entirely and actually strikes the surface its called a meteorite.

Rotation & Revolution

Revolution ~ it means when their closer to the sun it means shorter time for revolution. Farther from the sun means it'll be longer.

Rotation ~ when a object or something is spinning like a top. the planets spin and revolve at the same time when they orbit the sun.
