Our Universe • What is a galaxy? – An assembly of stars and related matter and gas, all held together by mutual gravity • What is a star? – A star is a sphere of plasma

Our Solar System • What is a planet? – An orbiting body large enough to become round due to its own gravity – Large enough to dominate the vicinity of its orbit

Our Solar System • Order of the planets – Terrestrial or Earth-like planets • Mercury, Venus, Earth, and Mars – Gas giants • Jupiter, Saturn, Uranus, and Neptune – Dwarf planet • Pluto

Our Universe • What is a moon? – Natural satellite of a planet • How old is the universe? – Started with the Big Bang – 14 billion years ago
