Eccentricity pt 1

Front

What is eccentricity in the context of orbits?

Back

Eccentricity is a measure of how much an orbit deviates from being circular. It ranges from 0 (perfect circle) to 1 (parabolic trajectory).

Front

What is the eccentricity of a perfect circle?

Back

0

Front

What are the two points around which an ellipse is drawn?

Back

Foci.

Front

Which planet has the least elliptical orbit among the following: Saturn, Mercury, Jupiter, Uranus?

Back

Uranus.

Front

During which month does the Earth move the slowest in its orbit?

Back

July.

Front

What is the range of eccentricity values for elliptical orbits?

Back

0 < eccentricity < 1.

Front

What does an eccentricity of 1 indicate about an orbit?

Back

It indicates a parabolic trajectory.

Front

What is the term for the point in an orbit where the object is farthest from the sun?

Back

Aphelion.

Front

What is the term for the point in an orbit where the object is closest to the sun?

Back

Perihelion.

Front

How does eccentricity affect the shape of an orbit?

Back

Higher eccentricity values result in more elongated orbits, while lower values result in more circular orbits.
