WebPhysical characteristics of Mercury:-Orbital period (1 Year): 88 days (0.24 year) Revolution period (1 Day): 58 earth days; Average orbital speed: 47.36 km/sec around the sun; Mean … WebAccording to Kepler’s laws, Mercury must have the shortest orbital period (88 Earth-days); thus, it has the highest orbital speed, averaging 48 kilometers per second. At the opposite extreme, Neptune has a period of 165 years and an average orbital speed of just 5 kilometers per second. All the planets have orbits of rather low eccentricity.

WebSep 12, 2024 · The orbital speed of 47 km/s might seem high at first. But this speed is comparable to the escape speed from the Sun, which we calculated in an earlier example. To give even more perspective, this period is nearly four times longer than the time that the Universe has been in existence.

WebThe orbital speed of Mercury is 47.8 km/sec (29.7 miles/sec). 3. Mercury has no atmosphere and no known satellites, perhaps because of its proximity to the Sun. 4. The … The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun). Since planets in the Solar System are in nearly circular orbits their individual orbital velocities do not vary much. Being closest to the Sun and having the most eccentric orbit, Mercury's orbital speed varies from about 59 km/s at perihelion to 39 km/s at aphelion.
