Mercury for example has essentially no axial tilt, but it has a 3/2 spin/orbit ratio which, effectively means that a day on Mercury lasts 2 years because it only spins 50% more rapidly …

Nettet22. nov. 2016 · The primary effect of the eccentricity is that the center of Mercury's orbit is quite far from the Sun. The orbit's center is about 0.0796 AU or 11.9 million km from … NettetThe semimajor axis of Mercury’s orbit—that is, the planet’s average distance from the Sun—is 58 million kilometers, or 0.39 AU. However, because its orbit has the high eccentricity of 0.206, Mercury’s actual distance from the Sun varies from 46 million kilometers at perihelion to 70 million kilometers at aphelion (the ideas and terms that … NettetWe will assume that Mercury’s orbital path is a circle. Mercury’s distance from the sun, 0.4 A.U. will be assumed to be 57,910,000 km. Mercury’s axial tilt is 2.11°. We will assume it is 0°. We will ignore any effects of parallax caused by the observer’s location on Earth. megan schieldmeyer cpa chicago
