Scientists have recently discovered one the smallest stars on record. How long will this star last compared to a larger star formed at the same time?

Question

Question 15 options:

A)

The smaller star will last longer than the larger star because it has a smaller chance of getting hit by an asteroid.

B)

The larger star will last longer than the smaller star because it uses fuel more efficiently.

C)

The larger star will last longer than the smaller star because it attracts more nebulae.

D)

The smaller star will last longer than the larger star because it burns less fuel.

Answer 1

The correct answer is:

D) The smaller star will last longer than the larger star because it burns less fuel.

Smaller stars, such as red dwarfs, are more efficient in their fusion processes and burn their fuel much more slowly than larger stars. As a result, they have much longer lifespans, often lasting billions of years, while larger stars burn through their fuel quickly and have much shorter lifespans.
