What's the perihelion distance of Mars?

Answer 1

The difference between the earth's closest approach to its star and its furthest distance away from it depends on how "out of round" or how eccentric is the earth's orbit around the Sun. Simplistically, this eccentricity varies periodically with a period of about 100 thousand years from 0.005 (almost perfectly circular) to about 0.058. The present eccentricity is 0.017 which yields a perihelion of about 91.405 million miles and an apelion of about 94.512 million miles. This varies from year to year.

Answer 2

The perihelion for Mars is 207 million km, or 1.38 astronomical units (www.universetoday.com/guide-to-space/mars/how-far-is-mars-from-the-sun/)


Depending on the Semimajor axis, and the orbital eccentricity. The formula goes something like this.

P= a(1-e)

Where P = Perihelion and A = Semimajor Axis and E = Eccentricity

e.g. if your semimajor axis is 1.524 AU and your orbital eccentricity is .093 then your formula would be

P= 1.524 (1 - .093)

which would be 1.382 AU

Answer 3

Aphelion (when the planet is furthest from the Sun) distance of Mars is 250 million Kilometers and Perihelion (when closest) distance is 208 million kilometers.

Next Martian aphelion is on Earth date Feb 15, 2012

Next Martian perihelion is on Earth date Mar 9, 2011

Answer 4

The Aphehelion is about 152 million km and the Perihelion is about 147 million km.

Hope this helps! xp

Answer 5

Each point is reached once a year as Earth revolves around the sun

Answer 6

The perihelion distance of Mars is approximately 206.62 million kilometers. This is the closest point that Mars gets to the Sun in its orbit.
