Circular earth orbit period
WebQuestion: 3. (10 pts) Spacecraft A and B are in the same circular earth orbit with a period of 4 hours. B is 6 km ahead of A. At t=0, B applies an in-track delta-v (retrofire) of 4 ms.

The orbital period is equal to that for a circular orbit with the orbit radius equal to the semi-major axis ... it is possible to plot an orbit from high earth orbit to Mars, passing close to one of the Earth's Trojan points ... WebThe hour circle is a subtype whereby it is expressed in hours as opposed to degrees, radians, or other units of angle. The hour circles make for easy prediction of the angle …
WebTo find the period of a circular orbit, we note that the satellite travels the circumference of the orbit 2 π r in one period T. Using the definition of speed, we have v orbit = 2 π r / T. … Webits orbital period is 24 hours. communication and weather satellites always appear at the same place in the sky because these satellites are. orbiting earth in a 24 hour period. …
WebNov 30, 2024 · The period of a satellite, or how long it takes to orbit the Earth one time, is dependent on its orbital altitude. Satellites in LEO, like the International Space Station, take about 90 minutes to orbit the Earth. Satellites in MEO take about 12 hours to do the same. Satellites orbiting at 35,786 km have a period precisely equal to one day.
