It was the first artificial (manmade) object to be placed in orbit around the earth. It started the space race between the USA and the USSR.
An object is placed into orbit around the earth by acheiving a velocity of 7,814 meters per second for a low earth orbit. Converted, this equals 17479.42 miles per hour. In simpler terms, gravity.
The sun.
An elliptical orbit is an elongated enclosed circle around the Earth. It is a path that gives the orbit its shape due to the gravitational pull between the Earth and the object. The orbit's shape varies depending on the object's velocity and distance from the Earth.
The proper orbit has not yet been attained. The Earth will orbit the Sun about once every 365 days.
A satellite, or the moon.
Orbit: as in the Earth orbits round the Sun.
Its means that if there is a planet, for example: Earth, The Earth is surrounded by the moon....so its actually means that a planet is surrounded by something else/A Planet
A satellite is any object that is in orbit around another object. The moon is a natural satellite of the Earth because it orbits around the Earth.
All part of the moon orbit around earth. Orbit mean moving around a centre object. It is different from rotation around its' axis for which, the moon show only the front part to earth.
No force orbits around the Earth. Forces do not orbit. The force that keeps material objects in orbit around the Earth is the mutual force of gravity between the Earth and the object.
A single Earth orbit refers to the path that a spacecraft or satellite takes around the Earth. It involves the object traveling in an elliptical or circular path due to the gravitational pull of the Earth. The time it takes to complete one orbit can vary depending on the altitude and speed of the object.
