Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How high is Geosynchronous orbit?Approximately 35,786 kilometers (22,236 miles) above Earth's mean sea level
2. What is the orbital period?Matches Earth's sidereal rotation period (23 hours, 56 minutes, 4.091 seconds)
3. What is the inclination for geostationary orbit?0 degrees relative to the Earth's equatorial plane
4. Why do we use geostationary satellites for TV?Because they stay fixed in the sky, TV antennas can stay still and always point at the same satellite. This makes it easier to receive clear signals.
5. How did the first geostationary satellite work?Syncom 3 was launched in 1964 and was the first satellite that stayed in a geostationary orbit. It helped broadcast the Tokyo Olympics, showing that the idea works.

Sidereal Day: The time it takes for Earth to rotate 360 degrees relative to the distant stars, approximately 23 hours and 56 minutes.
Centripetal Force: A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
Orbital Inclination: The angle between a satellite's orbital plane and a reference plane, typically Earth's equatorial plane.
Telecommunications: The transmission of information over significant distances by electronic means, such as radio, television, and the internet.
