How do you build a satellite?

How does a satellite stay in orbit?

A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.

How many satellites are there around the Earth?

Can we see satellites from Earth at night?

Spotting satellites It is this movement, as the satellite tracks across the night sky, that makes them possible to see. As with any sky-watching pastime, the darker the sky the better, so hobbyists will meet with better success further away from light-polluted urban areas.

How high are satellites in the sky?

approximately 35,786 kmGeosynchronous orbit (GSO): Orbits with an altitude of approximately 35,786 km (22,236 mi). Such a satellite would trace an analemma (figure 8) in the sky.
