The Planet Earth Our planet Earth is the fifth biggest planet out of eight planets in our Solar System, which orbiting the nearest star which is the Sun. The Earth moves in space with the speed of about 30 kilometers per second and needs one whole year to complete the whole circle. Moreover, the Earth rotates on its axis in every 24 hours. This makes the Sun appears as if it rises at dawn, passes through the sky and sets at dusk, giving us days and nights. Actually the Earth is not a perfect ball with equal measurements. The length of the equatorial line is 12,756 kilometers, while the distance between the North Pole and the South Pole is 12,714 kilometers.

Pluto When it was first discovered in 1930, Pluto was grouped into the Solar System as the ninth planet. In 2006, the International Astronomical Union (IAU) regarded this heavenly body as a dwarf planet. Pluto is a tiny planet, with an even smaller size than the Moon. It has an oval-shaped orbit around the Sun. Its period to complete the full orbit is equal with 248 years of the Earth's evolution. Its oval-shaped orbit causes differences in planet orders. Sometimes its orbit is closer to the Sun than Neptune’s. Pluto has three moons, named Charon, Nix, and Hydra. These three objects have the same natural color as the Moon, unlike Pluto's pinkish color. Some scientists even called Pluto and Charon as double planets, due to their similar sizes. Charon is only a bit smaller than Pluto.

Kuiper Belt Kuiper Belt is a collection of frozen objects extending from just beyond the orbit of the planet Neptune to well beyond the orbit of the former planet Pluto. The larger members of the belt are called Kuiper Belt Objects, or KBOs. Smaller members of the Kuiper Belt are usually reformed to as comets. The orbits of these objects show that the belt is actually disc-shaped. The existence of the Kuiper Belt was first predicted during the mid-20th century, most notably by Dutch American astronomer Gerard Kuiper. Kuiper and other astronomers expected that a debris belt, similar to the asteroid belt of rocky material that orbits the Sun between Mars and Jupiter but composed of icy material, might lie beyond Neptune. (From Microsoft Encarta, 2006)
