Question

3. Mention three main characteristics
of asteroids.​

Answer 1

Answer:

The rotation periods and shapes of asteroids are determined primarily by monitoring their changing brightness on timescales of minutes to days. Short-period fluctuations in brightness caused by the rotation of an irregularly shaped asteroid or a spherical spotted asteroid (i.e., one with albedo differences) produce a light curve—a graph of brightness versus time—that repeats at regular intervals corresponding to an asteroid’s rotation period. The range of brightness variation is closely related to an asteroid’s shape or spottedness but is more difficult to interpret.

Answer 2

Answer:

1) Asteroids are made up of metals and rocky material.

2) Asteroids are formed early in the history of the solar system about 4.5 billion years ago.
