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.

∙ 14y agoThe 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

How far away is Mars from the Sun in AU?
It varies, 1.66 AU at Aphelion and 1.38 AU at Perihelion.
Whats the normal temperature at Mars?
108 degress F
How many miles is earth away from mars?
The earth and Mars move in different orbits around the sun at different speeds. Therefore there is no single numerical answer to the question. There is however a minimum and maximum. See the link below.
How many miles is Mars away from the Earth?
Mars orbit is about 40 million miles further out than Earth's orbit. Because both planets are in constant motion, and because orbits are slightly elliptical (not perfectly circular), at any moment Mars can be from about 30 million miles away to 240 million miles.
How close does perihelion get to the sun?
Each planet has a slightly elliptical orbit and perihelion is the name given to the position in the orbit where it is closest to the Sun. So the Earth's average distance is 149.6 million km with an eccentricity of 1/60 which means that its distance varies 2.5 million km either side of the average. At perihelion, the distance is 147.1 million km about Jan. 3rd each year.
What is the distance from the sun to the fourth planet in your solar system?
The fourth planet from the sun is Mars. Aphelion is 249,209,300 km. Perihelion is 206,669,000 km
What speed must you travel in order to get to mars in order to get there in four years?
It depends. Because the distance between the Earth and the mars varies, the speed will also change if the time is given.If the mars is in perihelion and the earth in aphehelion, then you will have to go at speed of 1558.21917808 km/hr. But if the earth is in perihelion and the mars in aphehelion, then you will need a speed of 2916.66666666666........ km/hr in order to reach the moon in 4 years.
How close does Mars get the sun in Perihelion?
200145 km
How close does mars get to the sun in perihelion?
200145 km
What does perihelion ocur?
When an object orbiting the Sun is at its closest distance to the Sun, it is said to be in perihelion.
Angular distance from its last perihelion?
anomaly
What is the distance called when a planet's orbit is at it's farthest distance to the sun?
perihelion
Is perihelion the position of the earth when it is at its minimum distance from the sun?
yes
How far away is Mars from the Sun in AU?
It varies, 1.66 AU at Aphelion and 1.38 AU at Perihelion.
What word describes the closest distance the planet gets from the sun?
This is called perihelion.
Whats the period of revolution of Mars?
Mars has a rotational period of 24.6 hours.
What is the Position of planet defined by angular distance from last perihelion called?
An anomaly refers to the position of a planet or satellite that is defined by its angular distance from its last perihelion. It is considered an irregularity in the motion of a planet or satellite.
