Mercury
Mercury is the closest planet to the sun, and the smallest planet in the solar system.The name comes from the Roman god Mercury. Because Mercury is so close to the Sun (greatest angular distance is 28.3 °), it is difficult to observe, and observation is only possible in the early morning or late evening. Mercury's orbit has the largesteccentricity of the solar system. Like Mercury, Venus has no moons. Viewed fromEarth, Mercury will have phases like the Moon and Venus.

Pluto
Some places on the Pluto light is reflected much, in others hardly at all. The brightareas are probably composed of frozen nitrogen with small amounts of carbon monoxide and methane, while it is not yet sure what the dark parts composed. Theinterior of Pluto is probably composed of 70% rock and 30% ice.
