Front

What is retrograde rotation?

Back

Retrograde rotation is the rotation of a planet in the opposite direction to that of its orbit around the sun. For example, Venus and Uranus exhibit retrograde rotation.

Front

What is linear eccentricity in relation to an orbit?

Back

Linear eccentricity (c) is a measure of how much an orbit deviates from being circular, calculated as c = a * e, where 'a' is the semi-major axis and 'e' is the eccentricity.

Front

What is the formula to calculate linear eccentricity?

Back

c = a * e, where 'c' is linear eccentricity, 'a' is the semi-major axis, and 'e' is the eccentricity.

Front

What is the eccentricity of a circular orbit?

Back

The eccentricity of a circular orbit is 0.

Front

What is the significance of a planet's semi-major axis?

Back

The semi-major axis is the longest radius of an ellipse and represents the average distance from the planet to the star it orbits.

Front

What is retrograde motion?

Back

Retrograde motion is the apparent backward movement of a planet in the night sky, observed from Earth.

Front

What are the main components of a Jovian planet's atmosphere?
