"WebObjects in GSO have an orbital speed that matches the Earth’s rotation, yielding a consistent position over a single longitude. GEO is a kind of GSO. It matches the planet’s rotation, but GEO objects only orbit Earth’s equator, and from the ground perspective, they appear in a fixed position in the sky. " - Orbits and speed

WebJul 1, 2024 · The Earth orbits the sun at a speed of 67,000 miles per hour (107,800 kilometres per hour). That may seem fast, yet the sun moves through the Milky Way at far higher speeds. Current calculations place the sun’s speed at 500,000 miles per hour (800,000 kilometres per hour). That’s over seven times faster than the Earth’s orbital speed. 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.
