Web11 apr. 2024 · However, there is a discrepancy of 43 arcseconds per century, something Einstein's theory of general relativity accounts for. Using Einstein’s theory of curved space-time, the precession of Mercury’s perihelion should advance slightly more than under the predictions of Newton, since planets don’t orbit the sun in a static elliptical orbit. WebMercury is the biggest exception with an eccentricity of 0.21. (Or Pluto at 0.25). What's interesting, and what this post is all about, is that Mercury's orbit is not stationary. The ellipse slowly shifts around, it's perihelion point advancing by about 574 arcseconds (or 0.159 degrees) per century.

Web31 dec. 2024 · Mercury is visible low in the west after sunset in the second half of Jan. 2024. Credit: NASA/JPL-Caltech. This little planet orbits much closer to the Sun than Earth, meaning it also goes around the Sun much faster, completing its "year" in about a quarter of the time it takes Earth to go around once. And that's why we have a chance to view ... Webone real exception is Mercury, where the eccentricity is 0.205, and the distance from the Sun ranges between 28,600,000 miles at perihelion out to 43,500,000 miles at aphelion. This does make a marked difference; Mercury receives2ttimes more heat at perihelion thanit does at aphelion, but there are no Earth-typeseasons, because the axial tilt ... WebFor comparison, the Earth's distance at perihelion is 97% of the distance at aphelion. The sunlight striking Mercury at perihelion is 2.3 times more intense than at aphelion.
