Question

What is the radius of the earth's orbit around the sun?

1) 1.50×10¹¹ m
2) 1.50×10¹² m
3) 1.50×10¹⁰ m
4) 1.50×10⁹ m

Answer 1

The radius of the Earth's orbit around the Sun is 1.50×10¹¹ meters, which is also known as one astronomical unit (AU), a standard unit in astronomy.

Step-by-step explanation:

The radius of the Earth's orbit around the Sun, which is also the average distance between the Earth and the Sun, is 1.50×10¹¹ meters (1.50 x 10¹¹ m). This distance is referred to as one astronomical unit (AU), and it is the standard unit of measurement used in astronomy to describe distances within our solar system. The value of the Earth's orbital radius is crucial for calculations involving the Earth's motion around the Sun and is used in Kepler's laws of planetary motion to understand the dynamics of the solar system.
