Question
Allison is looking through a telescope at an object in space. The object looks like a very small planet, and it does not have a tail.If the object is orbiting the Sun and not the Earth, what is Allison most likely looking at? A. an asteroid B. a moon C. a galaxy D. a comet
Solution
Allison is most likely looking at A. an asteroid. Here's why:
- Moons orbit planets, not the Sun, so B. a moon can be ruled out.
- Galaxies are vast collections of stars and are much larger than a small planet, so C. a galaxy can be ruled out.
- Comets typically have tails due to the sublimation of ice as they approach the Sun, and the object Allison is observing does not have a tail, so D. a comet can be ruled out.
- This leaves us with A. an asteroid, which are small, planet-like objects that orbit the Sun.
