First of all, the speed of the Earth’s orbit around the Sun is 108,000 km/h, which means that our planet travels 940 million km during a single orbit. The Earth completes one orbit every 365.242199 mean solar days, a fact which goes a long way towards explaining why need an extra c...
In addition to the 24 satellites, the BDS constellation also has three satellites in geostationary earth orbit (GEO) and three in inclined geosynchronous orbit (IGSO). What's special about the extra six satellites is that they have a relatively fixed range of activity. This la...

Escaping Earth's orbit and seeing the planet from a distance is such an overwhelming experience that it is hard to come up with an adjective that is adequate to describe how it feels, according to retired astronaut Col. Mike Mullane, author of "Riding Rockets: The Outrag...
China's Mars rover Zhurong is ready for winter weather on the Red Planet, Chinese scientists told China Media Group on Friday. During the Martian wintertime, night temperatures on Mars may drop below minus 100 degrees Celsius with high probability of sandstorms, and the winter ...
The Moon Distance Calculator shows approximate times for when the Moon is closest to the Earth (perigee) and furthest from the Earth (apogee).
Geosynchronous orbits (GEO) – GEO satellites orbit Earth at an altitude greater than 22,223 miles (36,000 kilometers) and their orbital period is the same as Earth’s rotational period: 24 hours. Included in this category are geostationary (GSO) satellites, which remain in orbit above a fi...
to Mars is longer than Earth's orbit but shorter than Mars' orbit. Accordingly, we can estimate the time it would take to complete this orbit by averaging the lengths of Earth's orbit and Mars' orbit. Therefore, it would take about one and a half years to complete the elliptical orbit...
