What is the PERIHELION of a planet?

Back

The perihelion is the point in the orbit of a planet where it is closest to the Sun.

Front

How do you calculate the perihelion of a planet?

Back

Perihelion = Semi-major axis (a) * (1 - Eccentricity (e))

Front

What is the LINEAR ECCENTRICITY (c) of a planet?

Back

Linear eccentricity is the distance from the center of the ellipse to the focus, 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

Front

What is eccentricity in the context of planetary orbits?

Back

Eccentricity is a measure of how much an orbit deviates from being circular, ranging from 0 (circular) to 1 (parabolic).

Jupiter.

Front

What is retrograde motion?

Back

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

Front

Which planet has the hottest temperatures?

Back

Venus.

Front

What is the semi-major axis of a planet?

Back

The semi-major axis is half of the longest diameter of an ellipse, representing the average distance from the planet to the Sun.

Front

What is the significance of the semi-major axis in astronomy?

Back

The semi-major axis is crucial for determining the size of a planet's orbit and calculating its orbital period.
