It varies: The planets closer to the Sun move faster (Kepler's Third Law). Mercury is fastest; according to Wikipedia, its average orbital speed is 47.87 km/s. Multiply that by 0.6 to get the approximate speed in miles per second.
No, the speed of light is 186,282.4 miles per second. The speed of sound at sea level is about 0.2114 miles per second.
The speed of sound at sea level is about 0.211 miles per second.
The speed of light is 186,000 miles per second in a vacuum.
The speed of light is 186,282 miles per second.
The speed of the light is 3.10^8 miles per second.what is the speed in miles per hour
earth orbital speed is 30 kilometers per second!!
venus
there is no answer people sorry!!
Jupiter, and planets further away from the Sun than Jupiter.
(Escape velocity) at least 7 miles ber second. Close-Orbital velocity is about 5 miles per second.
There are two reasons. First, since they are farther from the sun they have longer orbital path. Second at a greater distance from the sun the sun's gravity is weaker, giving the outer planets a slower orbital speed.
Planet Mars orbits the sun at an average velocity of 14.96 miles per second.
Because according to Kepler's laws the orbital speed of a planet is proportional to the square root of the reciprocal of the distance: v = d-½.
The ones closest to the Sun.
Pluto isn't a planet anymore! : P don't pay any attencion to it
The earth's mean orbital velocity is 18.5 miles (29.8 km) per second.
The orbital speed goes with the inverse square-root of distance. The Earth at 1 astronomical unit goes at 18.5 miles per second, so Mars at 1.52 astronomical units travels at 18.5/sqrt(1.52) or 15 miles/sec.
