What is the orbital radius of Mars in KM?

“Because of Mars’s relatively elongated orbit, the distance between Mars and the Sun varies from 206.6 million to 249.2 million km (128.4 million to 154.8 million miles). Mars orbits the Sun once in 687 Earth days, which means that its year is nearly twice as long as Earth’s.”

How do you find the orbital radius of a planet?

“Kepler’s Third law can be used to determine the orbital radius of the planet if the mass of the orbiting star is known (R3=T2−Mstar/Msun, the radius is in AU and the period is in earth years).”

What is the orbit of Mars?

“Mars has an orbit with a semimajor axis of 1.524 astronomical units (228 million kilometers), and an eccentricity of 0.0934. The planet orbits the Sun in 687 days and travels 9.55 AU in doing so, making the average orbital speed 24 km/s.”

What is the axis angle of Mars?

“Unlike Earth, the obliquity (or tilt) of Mars changes substantially on timescales of hundreds of thousands to millions of years. At present day obliquity of about 25-degree tilt on Mars’ rotational axis, ice is present in relatively modest quantities at the north and south poles (top left).”

Has Mars changed its rotation?

“That is, Mars appears to move from west to east from one night to the next. Every two years or so, there are a couple of months when Mars’ position from night to night seems to change direction and move east to west. This strange behavior was very puzzling to early skywatchers.”
