The measure of how circular or elliptical an orbit is.		Inclination
The point in the orbit of an object (such as a satellite) orbiting the earth that is at the greatest distance from the center of the earth.		Eccentricity
The "tilt" of the orbit relative to the equator.		Semi-Major Axis
The point in the orbit of an object (such as a satellite) orbiting the earth that is the closest to the center of the earth.		Apogee
Describes the size of an orbit. For circular orbits, altitude is often used in place of this term.		Perigee

The value of which orbital parameter is 0 when the satellite is at its perigee point and 180 when the satellite is at apogee?

Label the position indicated with the A in the pictured orbit.

Both size (semi-major axis and/or altitude) and eccentricity play an important role in determining the period of the orbit.

True

False

The Voyager 1 spacecraft was launched in 1977 to explore the solar system and beyond. In 2008, it was entering the region between our solar system and interstellar space known as the heliosheath. It is the furthest manmade object from the Eatch and it continuing its journey into the unknown. Based on what you have learned about orbital elements, the eccentricity of Voyager is greater than 1.

True

False

This philosopher believed that everything rotates around the Earth.

This philosopher was the first to propose heliocentric theory.

A satellite designed to take images to monitor the polar ice caps would have an inclination of ___ degrees.

A satellite crosses the equator in a northerly direction at 0 degrees longitude. On its next northerly pass over the equator it crosses at 23 degrees west longitude. How many minutes did it take this satellite to complete one orbit?

A circular orbit has an apogee roughly twice the altitude of its perigee.

True
