Question

multiple-choice question how does a planets distance from the sun affect the size/length of its orbit? the closer a planet is to the sun, the longer its orbit. the further a planet is from the sun, the longer its orbit. the further a planet is from the sun, the shorter its orbit. rewatch

Explanation:

A planet's orbit around the Sun is approximately elliptical (or nearly circular for many planets). The length of the orbit (circumference for a circular approximation, or the major axis - related length for an ellipse) depends on the average distance from the Sun (semi - major axis for an ellipse, radius for a circle). Using the formula for the circumference of a circle $C = 2\pi r$ (where $r$ is the radius, analogous to the average distance from the Sun), if the distance $r$ (or semi - major axis) increases (the planet is further from the Sun), the length of the orbit $C$ (or the length related to the ellipse) will increase. So the further a planet is from the Sun, the longer its orbit. The first option is wrong because a closer planet (smaller $r$) would have a shorter orbit. The third option is wrong as a further planet should have a longer, not shorter, orbit.

Answer:

B. The further a planet is from the Sun, the longer its orbit. (Note: Assuming the options are labeled A, B, C as per typical multiple - choice with the first option as A, second as B, third as C. If the original options had different labels, adjust accordingly, but based on the given text, the correct statement is "The further a planet is from the Sun, the longer its orbit".)
