Planet

A planet is a celestial body, apparently bigger than poor little Pluto, orbiting a star. They typically have semi-solid metalic core, and the rest of the planet can be either gaseous like Jupiter and Saturn, or more dense and solid like Earth and Mars.

A partial lunar eclipse as seen in Manila on December 10, 2011. A lunar eclipse occurs when the moon, following its orbit around Earth, passes directly behind our planet as seen from the sun.

The Earth's shadow is cast upon the moon during the last total lunar eclipse of 2011 as seen from the San Gabriel Valley east of Los Angeles on December 10, 2011. A lunar eclipse occurs when the moon, following its orbit around Earth, passes directly behind our planet as seen from the sun.

IN SPACE - UNSPECIFIED: In this handout illustration made available on December 5, 2011 by NASA, a diagram compares our own solar system to Kepler-22, a star system containing the first 'habitable zone' planet discovered by NASA's Kepler mission. The habitable zone is the sweet spot around a star where temperatures are right for water to exist in its liquid form. Liquid water is essential for life on Earth. The diagram displays an artist's rendering of the planet comfortably orbiting within the habitable zone, similar to where Earth circles the sun. Kepler-22b has a yearly orbit of 289 days. The planet is the smallest known to orbit in the middle of the habitable zone of a sun-like star and is about 2.4 times the size of Earth.

IN SPACE - UNSPECIFIED: In this handout illustration made available on December 5, 2011 by NASA, the Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star is digitally illustrated. For the first time NASA's Kepler mission has confirmed a planet to orbit in a star's habitable zone; the region around a star, where liquid water, a requirement for life on Earth, could persist. The planet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habit. Clouds could exist in this earth's atmosphere, as the artist's interpretive illustration depicts.
