Question

the distance from the earth to a planet in the solar system is A4U what do you mean by this​

Answer 1

ANSWERS:

It rules out the planet being Mercury, Venus, or Mars, because the farthest it can ever be from any of them is less than 3 au.

It also rules out Saturn, Uranus, and Neptune, because the closest it can ever be to any of them is greater than 8 au.

That leaves Jupiter. At perihelion, it’s just under 5 au from the Sun, which puts Earth’s closest approach to it at about 4 au.

So, it means that the planet is Jupiter.
