· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

18.1: Introduction to the Solar System

The inner solar system and asteroid belt is on the upper left. The upper right shows the outer planets and the Kuiper belt. Eventually, the planetesimals formed protoplanets, which grew to become the planets and moons that we find in our solar system today. Because of the gravitational sorting of material, the inner planets — Mercury

Moons of the Solar System

moons, yet embedded in Saturn''s rings are distinct moons or "moonlets." Small "shepherd" moons help keep the rings in line. Saturn''s moon Titan, the second largest in the solar system, is . the only moon with a thick atmosphere. Beyond Saturn, Uranus has 27 known moons. The inner moons . appear to be about half water ice and half rock.

How Many Moons Does Each Planet Have?

Earth is the first planet from the inner solar system to possess a natural satellite. Earth''s natural satellite is called Moon because at the time of its discovery our moon was the only one known. We then move on to Ganymede, the largest moon in our solar system. With a diameter of 3,273 miles, Ganymede is so huge that it boasts its own

Chapter 1: The Solar System

Earth''s Moon orbits the planet once every 27.3 days at an average distance of about 384,400 km. The moon''s orbital distance is steadily increasing at the very slow rate of 38 meters per millennium. Its distance at this point in its history makes the moon appear in the sky to be about the same size as the Sun, subtending about half a degree.

Which planets are in the inner Solar System?

In the inner Solar System, we find the “Inner Planets” – Mercury, Venus, Earth, and Mars – which are so named because they orbit closest to the Sun. In addition to their proximity, these planets have a number of key differences that set them apart from planets elsewhere in the Solar System.

Do planetary moons have atmospheres?

They are generally solid bodies, and few have atmospheres. Most planetary moons probably formed out the discs of gas and dust circulating around planets in the early solar system. There are hundreds of moons in our solar system – even asteroids have been found to have small companion moons.

How are planetary moons formed?

They are generally solid bodies, and few have atmo-spheres. Most of the planetary moons probably formed from the discs of gas and dust circulating around planets in the early solar system. As of September 2009, astronomers have found at least 145 moons orbiting planets in our solar system.

What are the characteristics of the inner planets?

The relatively small inner planets have solid surfaces, lack ring systems, and have few or no moons. The atmospheres of Venus, Earth, and Mars are composed of a significant percentage of oxidized compounds such as carbon dioxide.
