It means that an object remains in a stable orbit around a central object. For example the Earth stays in a stable near-circular orbit around the Sun although it is continuously moving at around 18 miles per second in a direction that is along the ecliptic and at right angles (approximately) to the direction of the Sun.
Stay in orbit
For a planet to stay in it's orbit the forces must be in balance.
Sir Isac Newton was the scientist who discovered why the planets stay in orbit.
Gravity holds satellites in orbit.
Interia and gravity combine to make a planet stay in an orbit.
They stay in orbit because of the suns gravitational pull.
paul bunyan swings his ax at the electrons and they stay in orbit
17,500 mph is required to stay in orbit.
The planets stay in orbit because of the gravitational attraction between the individual planets and the sun. Their rotational velocity makes them stay in a stable orbit instead of spiraling into it.
The reason that satellites stay in orbit around Earth is because of two factors. Velocity and the gravitational pull between the satellite and the Earth.
Can an object stay in orbit around Saturn somewhere else besides the rings
