solar system

1. Often Solar System The sun together with the planets and all other bodies that orbit the sun, including moons, asteroids, and comets. See more at nebular hypothesis.
2. A system of planets or other bodies orbiting another star.
Did You Know? Usually, we think of the solar system as simply including the sun and the planets. We may even remember the moons that revolve around several planets. But actually, the solar system contains billions of other objects as well and extends far beyond the orbit of Neptune. Several hundred thousand asteroids have been discovered, and countless smaller asteroids, including the chunks of debris formed during the collision of larger bodies, are out there as well. These smaller particles may come near Earth—as many as a billion meteors, most the size of a speck of dust, cross through our planet's atmosphere each day. Astronomers have recorded more than 800 comets passing through the inner part of the solar system. Billions more, however, lie in the area surrounding the solar system, in the far reaches of the swarm of comets known as the Oort cloud or in the disk of debris known as the Kuiper belt. All of these objects travel around the sun at high speeds in paths called orbits. Some of these orbits, like those of the planets near the sun, are almost circular. Other orbits, like those of comets that make their way in among the planets, are stretched out into long ellipses.

Our solar system consists of nine planets. The diameter of each planet, at its equator, is given here. a Mercury 3,031 mi (4,878 km) b Venus 7,521 mi (12,104 km) c Earth 7,926 mi (12,756 km) d Mars 4,222 mi (6,795 km) e Jupiter 88,732 mi (142,800 km) f Saturn 74,565 mi (120,000 km) g Uranus 31,566 mi (50,800 km) h Neptune 30,137 mi (48,500 km) i Pluto 3,725 mi (5,995 km)
