Web8 apr. 2015 · At the time when Apollo 11 left Earth orbit for the Moon, it was traveling at approximately 36,700 ft./sec. Its velocity was slowed all the way to the Moon, by the Earth's gravity. On the return journey, the Earth's gravity accelerated the Command Module, so that just before it hit the Earth's atmosphere, it was traveling approximately 36,300 ... Web13 sep. 2011 · Here F = 1200 mm is the focal length of the telescope's main mirror, and D = 3,476 km is the Moon's diameter. Since d and F both have units of millimeters, the ratio F/d is a pure number — the units of d and F cancel out. In fact, this ratio is also the ratio of the Moon's distance to its diameter. To get the Moon's actual distance, just multiply this …

WebThe first orbit was an elliptical orbit, with an apolune of 1,008 nautical miles (1,867 km; 1,160 mi) and a perilune of 102.1 nautical miles (189.1 km; 117.5 mi). Then the orbit was … WebIts mean orbital distance is about 354,800 km (220,500 miles) from the planet. Also unusual for a large moon is Triton’s orbital inclination—the plane of its orbit is tilted more than 157° to Neptune’s equator. Triton rotates once on its axis every 5.877 days, which is the same time that it takes to revolve around Neptune. WebSo although Earth orbits the sun at 66,600 mph, and the sun orbits the Milky Way at 514,500 mph, our solar system's speed relative to the CMB is about 827,000 mph. … graphics setclip
