Proximity to the sun

The distance from Earth to the sun is called an astronomical unit, which is used to measure distances throughout the solar system. Mercury is the closest planet to the sun. As the mass of the Sun goes down, our orbit gets proportionally bigger.

However, over the entire main sequence lifetime of the Sun (about billion years), the Sun will only lose about 0. The distance between Earth and Sun is probably the least critical with respect to the average temperatures on Earth.

The Sun is at an average distance of about 9000miles (1million kilometers) away from Earth.

Like all of the other planets in our Solar System, Earth does not travel .

Keep in mind that this distance is an average. At the closest point of its orbit, called . Strong Evidence Points to Earth s. All about the planets in our Solar System. One amazing fact-it is not the hottest planet , venus is because of the gas around the venus which captures the heat and all make the . Proximity to the moon, probably not. The eight planets in our solar system each occupy their own orbits around the Sun. They orbit the star in ellipses, which means their distance to the sun varies depending on where they are in their orbits.

Mars orbits the Sun at an average distance (semi-major axis) of 2million km ( 14million mi), or 1. Our solar system has eight planets. Planets orbit around the sun , as do their moons, asteroids, comets and other rocks and gas. The planets, each with their own unique features, are located at different distances from the sun , . Uranus is more than times farther from the Sun than Earth is. Because its orbit is elliptical, its distance from the Sun changes depending on where it is in its orbit. The closest Uranus gets to the Sun is 69800miles or . The average distance of Venus from the Sun is 6239miles or 10209km.

Since Venus travels in an elliptical orbit around the Sun , its distance from the Sun varies throughout its year from 6780miles (10470km) to 6690miles (10940km). At perihelion, the Earth is about 147. The difference between the two is 004km, ( percent), and not enough to cause the seasons.
