Astronomers have made guesses of the distance between the Sun and Earth for millennia, but only in recent centuries have they been able to make accurate predictions. Aristarchus of Samos made one of the earliest estimations, claiming that the sun was 20 times as far from the Earth as the moon while in reality the true ratio is 390 times. In 1659 Christiaan Huygens made one of the earliest accurate measurements, claiming that the distance was 24,000 times the radius of the Earth while the true value is 23,455 times as much. However, most discredit this finding as luck as his calculation was based on numerous unproven and false assumptions.
Jean Richer and Giovanni Domenico Cassini made what is believed to be the first accurate measure that was properly justified in 1672. By making measurements relative to Mars from two locations, that calculated that the sun was 21,700 Earth radii away. Better tools over the years have allowed us to slowly increases the accuracy of that measure ever since.

How far is earth from the edge of the solar system?
29770600000km I found this by taking the distance from the earth to the sun from the distance from the sun to the heliosphere (edge of solar system)
How far is the earths moon from mercury?
Varying from the the distance from the Earth to the Moon + the distance from the sun to the earth + the distance from mercury to the sun, to the distance from the earth to the sun - the distance from mercury to the sun - the distance from the earth to the moon
Is it posseble for the sun to be found between Earth and the moon?
The distance from Earth to the sun is much greater than from Earth to the moon. It is not possible that the sun would be between Earth and the moon.
Distance from the earth?
distance earth from the sun
Earth and sun distance?
The distance from Sun to Earth is about 150 million kilometers.
What is the distance from sun to Earth in Au's?
An AU, or astronomical unit, is defined as the average distance from Earth to the Sun. Therefore, the distance from Earth to the Sun equals 1 AU.
An astronomical unit is the average distance between the?
One AU is the distance between the Earth and the Sun.
What is this distance from earth to the sun in atomic units?
The distance to the sun is one astronomical unit (AU). The earth-sun distance is the basis for the AU.
What do you call it when earth is at its max distance from sun?
the max distance from earth to sun is known as aphelion
Which is the closest distance of the earth from the sun?
it is about 92 million miles from the earth to the sun at its closest distance.
What is the distance of the sun called?
I think you mean the distance from the Earth to the Sun. This distance is measured in Astronomical Units (AU)
How far away is the sun in miles?
It varies - the moon orbits the Earth so the distance will change depending on Earth's distance from the sun as well as the moon's distance from the Earth. The minimum distance from the moon to the sun is when the Earth is closest to the sun and the moon is in new moon phase (meaning its closer to the sun than the Earth). The distance from the moon to the sun is: Earth's distance at perihelion - moon's distance from Earth at apogee. This works out to 146,692,370 km. The maximum distance from the moon to the sun is when the Earth is farthest from the sun and the moon is in full moon phase. The distance from the moon to the sun is Earth's distance at aphelion + moon's distance from Earth at apogee. This works out to 150,503,400 km.
