In other words, find an orbit with a period of 24 hours. Recalling the relationship between force and period of circular motion, the period, radius and mass of the satellite are related to the ...

If I wanted to show a longer time period, ... You might notice that the distance from the Earth to the Sun changes. I put in an initial velocity to give the Earth a circular orbit.

In other words, it was only in the "right" region of space in that time frame for astronomers to capture it. Blunt says that originally the planet may have started with a roughly circular orbit ...

Once in a lower and more circular orbit, the space plane will then jettison its service module components. This means the components will remain in orbit for a much shorter period of time than if ...
