The Astronomical Unit (AU) is a standard measure of distance used in astronomy, defined as the average distance from the Earth to the Sun, approximately 93 million miles or about 150 million kilometers. Mercury, the closest planet to the Sun, has an average orbital speed of about 47.87 kilometers per second (or about 29.74 miles per second). This high speed is due to its proximity to the Sun and the influence of its gravitational pull.

Uranus requires 84 years to circle the sun Find Uranus' orbital radius as a multiple of Earth's orbital radius?
Uranus' orbital radius is about 19.22 times the average distance from Earth to the Sun (1 astronomical unit). This makes Uranus' average distance to the Sun approximately 19.22 astronomical units.

What is the abbreviation for astronomical unit?
The abbreviation for astronomical unit is AU. An astronomical unit is a unit of length roughly equal to the average distance from the Earth to the Sun, used to measure distances within our solar system.
What is the radius of an astronomical unit compared to?
One Astronomical Unit (abbreviated AU) is the distance from the Sun to the Earth, which is 93 million miles. So the Earth's orbital radius 1 AU.
What is Mars' speed of travel in miles per hour?
The orbital speed goes with the inverse square-root of distance. The Earth at 1 astronomical unit goes at 18.5 miles per second, so Mars at 1.52 astronomical units travels at 18.5/sqrt(1.52) or 15 miles/sec.
Uranus requires 84 years to circle the sun Find Uranus' orbital radius as a multiple of Earth's orbital radius?
