Question

planets that are farther from the sun ______. * image of solar system with labeled planets (mercury, venus, earth, mars, jupiter, saturn, uranus, neptune) and dwarf planets (ceres, pluto, haumea, makemake, eris) have longer days have warmer temperatures orbit the sun faster orbit the sun slower

Explanation:

To solve this, we analyze each option:

• "Have longer days": A planet's day length (rotation period) is not directly related to its distance from the Sun. For example, Venus is close to the Sun but has a very long day, while Jupiter (farther) has a short day. So this is incorrect.
• "Have warmer temperatures": Planets farther from the Sun receive less solar radiation, so they are generally colder, not warmer. Incorrect.
• "Orbit the Sun faster": According to Kepler's laws of planetary motion, the orbital speed of a planet is inversely related to its distance from the Sun (specifically, $v \propto \frac{1}{\sqrt{r}}$ where $r$ is the orbital radius). So farther planets should orbit slower, not faster. Incorrect.
• "Orbit the Sun slower": Using Kepler's third law (or the relationship between orbital speed and distance), as a planet is farther from the Sun, its orbital speed decreases. For example, Mercury (closest) orbits quickly, Neptune (farther) orbits slowly. This is correct.

Answer:

D. Orbit the Sun slower
