Planetary characteristics
Mercury, Venus, Mars, Jupiter and Saturn can be seen without a telescope. Ancient Greece called them planets or "wanderers" because these celestial bodies seemed to run on a fixed star background. Although Uranus can sometimes be seen without a telescope, ancient astronomers could not distinguish it from stars.
Planets can be classified in different ways. According to one scheme, the orbit diameter of Mercury and Venus around the sun is smaller than that of the Earth around the sun, and they are called inner planets. The so-called extraterrestrial planets refer to those planets whose orbit diameter around the sun is larger than that of the earth.
