Earth in space
Nine planets of the solar system arrayed from bottom to top in order of their distance from the Sun (not shown). The four small, rocky planets of the inner solar system are Mercury, Venus, Earth and Mars. Then come the four large, gas giant planets of the outer solar system Jupiter, Saturn, Uranus and Neptune. Finally, Pluto is a Dwarf planet of rock and ice that orbits at the outer edges of the solar system.
This view of the rising Earth greeted the Apollo 8 astronauts as they came from behind the Moon after the lunar orbit insertion burn. The photo is displayed here in its original orientation, though it is more commonly viewed with the lunar surface at the bottom of the photo. Earth is about five degrees left of the horizon in the photo.
