Final answer:
The average distance from Earth to the Sun is called an Astronomical Unit (AU), which is about 150 million kilometers.
Step-by-step explanation:
The average distance from Earth to the Sun is called an Astronomical Unit (AU), which is about 150 million kilometers. Astronomers use the AU as a standard measuring stick to express distances within the solar system. For example, Pluto orbits at an average distance of 40 AU from the Sun, and the dwarf planet Eris is roughly 96 AU away.
The giant planets in our solar system, like Jupiter and Saturn, are very far from the Sun. Jupiter is more than five times farther from the Sun than Earth's distance (5 AU), and Saturn is about twice as far away as Jupiter (almost 10 AU).
It is important to note that the distances in the solar system are vast, and even though the AU is a large unit, it is still not sufficient for measuring distances to stars.
