Answer 1

Red supergiants live for millions of years.

Step-by-step explanation:

Red supergiants live for millions of years.

According to the information provided, Betelgeuse, a red supergiant, is only 10 million years old and is already nearing its death throes. This indicates that red supergiants have relatively short lifespans compared to the age of our Sun, which is 4.5 billion years old.
