Planet by a long way.
They vary but in our solar system the largest is Jupiter and it's 66,854km across the middle.
A light second is the distance travelled by light in a second = 299,792.5km
A star can be lots of different sizes - our Sun is = 1,391,980km
An AU is the distance from the Earth to the Sun = 149,598,000 km
Since all other things are equal, it will take a year to go around the star. The mass of the planet hardly has any effect on its orbit - unless this mass is significant, compared to the star.
Saturn is 9.54 A.U from the sun (1AU= Earth's distance from the sun)
1 Astronomical unit is the mean distance from Earth to Sun and is exactly 149,597,870,700 metres or 92,955,807.273 miles.
Mercury and Venus are always less than 1 AU from the sun. The Earth's orbit averages 1 AU from the sun, so sometimes the Earth is less than 1 AU, sometimes it is more.
1) The astronomical unit is the mean distance from Earth to the Sun only. However you can measure the distance to Mars in these units. 2) Unfortunately, that distance keeps changing as the planets move in their orbits.

Divide kilometers by 149,597,871. (1AU = 149,597,871km)
52 Astronomical Units is 7,779,089,292 kilometers. (1AU = 149,597,871km)
$1AU = approx 4 francs
Well, the proton is positive and weighs 1AU and the Neutron has a neutral charge and also weighs 1AU while the Electrons weigh less than an AU and are negative. The proton and neutron are in the nucleus and the leectrons hover around the nucleus in eliptical patterns.
Probably AUs or Astronomical Units. 1AU= 93 million miles or about 150 million km. 1AU is the distance from the Earth to the Sun.
By definition, the planet Earths average distance is 1 AU (astronomical Unit) from the sun. This is about 93 million miles or 150 million km.
There is no need to change astronomical unit into Kilometres cause 1AU = 1.495978707 x 108 kilometres
1 Astronomical unit is the mean distance from Earth to Sun and is exactly 149,597,870,700 metres or 92,955,807.273 miles.
An astronomical unit (AU) is the average distance between Sun and Earth. This is approximately 150 million kilometers.
1 Astronomical Unit or 1AU is the average distance between the Sun and the Earth. It is approximately 149,598,000 km.
