Q:

How far away are all the planets from the Sun?

A:

Mercury, which is the closest planet to the Sun, is 36 million miles from the sun, and Neptune, the eighth planet from the Sun, is approximately 2,790,000,000 miles away. The rest of the planets fall in between that range.

The Earth is about 93 million miles away from the star, or 1 astronomical unit. This makes it the third planet from the Sun. Venus, the second closest planet to the Sun, is about 68 million miles from the Sun, or 0.73 AU. Mars, the fourth closest planet to the Sun, is about 128 million miles from the star, or 1.38 AU. Jupiter, a gas giant and the largest planet, is the fifth planet from the Sun. It is about 484 million miles from the Sun, or 5.20 AU. Saturn, the sixth closest planet to the Sun, is about 887 million miles from the Sun, or 9.54 AU. Uranus, the seventh planet, is about 20 AU from the star, or approximately 1,860,000,000 miles.

Astronomers have demoted Pluto to a dwarf planet, but it was once classified as the ninth planet from the sun. Pluto is about 4.6 billion miles from the Sun, or 49 AU at aphelion. Pluto's orbit is so eccentric that there are times when it is closer to the star than Neptune.

  • Q:

    How far are the planets from the sun?

    A:

    The eight described planets all orbit the Sun at different distances; Mercury is the closest planet to the sun, followed by Venus, then Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The distances of the planets are normally measured in kilometers, because scientists use metric measurements. However, scientists also use a unit called an “astronomical unit,” which is equal to the distance between Earth and the sun.

    What are some facts about Mars?

    A:

    Mars is 142 million miles from the Sun and takes 687 Earth days to complete one orbit around the sun, according to the National Aeronautics and Space Administration. The average surface temperature on Mars is -81 degrees Fahrenheit, and the small red planet has a much weaker gravitational pull than that of Earth. Mars also has 15 percent of the volume of Earth.
