Earth perihelion and aphelion
WebAnswer: The Kepler's laws of planetary motion, the orbital speed of a planet changes as it orbits the Sun, with the highest speed occurring at the point of closest approach (perihelion) and the lowest speed occurring at the point of farthest approach (aphelion). To determine the orbital speed of the Earth at perihelion, we can use the ... WebJul 10, 2004 · The Sun-Earth distance at aphelion varies slightly from year to year depending on the relative positions of the Sun, Earth, and Moon, and the location of the solar system barycentre (centre of mass), which is affected by the positions of all the planets, principally Jupiter and Saturn.

WebDec 8, 2024 · Mars' orbit is more elliptical than Earth's, so the difference between perihelion and aphelion is greater. Over the past centuries, Mars' orbit has been getting more and more elongated, carrying the planet even nearer to the sun at perihelion and even farther away at aphelion. So future perihelic oppositions will bring Earth* and Mars …
