Answer 1

What does it mean when the orbital eccentricity of a planet is close to 1?(1 point) Responses its orbit is a highly elongated ellipsis. its orbit is a highly elongated ellipsis. Its orbit crosses over the orbit of another planet. Its orbit crosses over the orbit of another planet. Its orbit is not closed around a fixed point Its orbit is not closed around a fixed point its orbit is close to another planet's

Answer 2

Astronomers discover a new comet that follows a highly elliptical orbit. What is its eccentricity likely to be?(1 point) Responses 0.1500 0.1500 0.0014 0.0014 0.0009 0.0009 0.9200

Answer 3

The orbital eccentricity of Venus is approximately **0.0068**. This low value indicates that Venus has a nearly circular orbit around the Sun.

Answer 4

When the orbital eccentricity of a planet is close to 1, it means that **its orbit is a highly elongated ellipse.** Eccentricity measures how much an orbit deviates from being circular, with values closer to 1 indicating more elongated orbits.

Answer 5

If the comet follows a highly elliptical orbit, its eccentricity is likely to be close to **0.9200**. Eccentricities near 1 indicate elongated orbits, characteristic of comets with highly elliptical paths.
