What is the exact distance between the sun and earth?

Answer 1

There isn't an exact distance as the Earth's orbit is not perfectly circular. The Astronomical Unit (AU) is based on the average distance 1 AU = 149,597,870.7 km exactly.

With a perihelion distance of roughly 147,098,000 km and an aphelion distance of roughly 152,098,000 km, the Earth's orbit is roughly elliptical.

The average distance between the Earth and the Sun has been used to define the Astronomical Unit (AU), which is currently an international standard and is precisely 149,597,870.7 km.

Because of their elliptical orbits, the exact distance between the Sun and Earth varies slightly, but on average it is approximately 149.6 million kilometers (93 million miles).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
