Draggable item		Corresponding Item
Describes the size of an orbit. For circular orbits, altitude is often used in place of this term.		Inclination
The measure of how circular or elliptical an orbit is.		Eccentricity
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.		Semi-Major Axis
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.		Apogee
The "tilt" of the orbit relative to the equator.		Perigee

1

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

1

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.

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.
