kilometers
The speed of light is normally used to tell the distance between planets. The distance between cities is measured in miles.
Planets are usually measured in miles or kilometres.
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
they are measured in AU
The parallax method can be used to calculate the distance between planets and other celestial bodies. The formula for this is d(pc) = 1/p where p is parallax measured in arcseconds.
The distances between the inner planets is smaller than the distances between the outer planets.
Interplanetary distances are measured in either kilometers or in miles. For the distant planets, some measures are measured in Astronomical Units, where one AU is the distance between the Sun and the Earth. So, 1 AU = 93,000,000 miles.
Between Planets was created in 1951.
The inner planets are closer together than the outer planets are.
Earths diameters is a straight line through the middle of the Earth. That is how the size of planets is measured.
Between Planets has 222 pages.
