Please provide values below to convert Earth's polar radius [R_p] to Earth's distance from sun [AU_dist], or Convert Earth's distance from sun to Earth's polar radius.
How to Convert Earth's Polar Radius to Earth's Distance From Sun
1 R_p = 4.24922645640303e-05 AU_dist
Example: convert 15 R_p to AU_dist:
15 R_p = 15 × 4.24922645640303e-05 AU_dist = 0.000637383968460455 AU_dist

Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
Earth's Distance From Sun
The Earth's distance from the Sun varies throughout the year. The average distance is defined as one astronomical unit (AU), which is about 149.6 million kilometers.
History/Origin
The measurement of the Earth-Sun distance has a long history, with early estimates made by ancient Greek astronomers. Modern measurements are highly precise.
Current Use
The Earth-Sun distance is a fundamental unit in astronomy and is used to measure distances within the solar system.
