1- What are your plans for tomorrow?
2- The solar system consists of the
Sun; the nine planets, more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are probably also many more planetary satellites that have not yet been discovered.)
The inner solar system contains the
Sun, Mercury, Venus, Earth and
Mars.
The main "asteroid belt" lies between the orbits of Mars and
Jupiter. The planets of the outer solar system are Jupiter, Saturn, Uranus, Neptune and
Pluto......
One way to help visualize the relative sizes in the solar system is to imagine a model in which everything is reduced in size by a factor of a billion. Then the model Earth would be about
1.3 cm in diameter (the size of a
grape). The
Moon would be about 30 cm (about a foot) from the Earth. The
Sun would be
1.5 meters in diameter (about the height of a man) and 150 meters (about a city block) from the Earth. Jupiter would be 15 cm in diameter (the size of a large grapefruit) and 5 blocks away from the
Sun. Saturn (the size of an orange) would be 10 blocks away; Uranus and Neptune (lemons) 20 and 30 blocks away. A human on this scale would be the size of an atom but the nearest star would be over 40000 km away.
