Answer 2

Answer:

⇒ A red dwarf is the smallest and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.

• ${\boxed{\green{\text{Formation and characteristics}}}}$

⇒ Red dwarfs form like other main-sequence stars. First, a cloud of dust and gas is drawn together by gravity and begins rotating. The material then clumps at the center, and when it reaches the critical temperature, fusion begins.

• ${\boxed{\orange{\text{How long will red dwarfs last?}}}}$

⇒ A red dwarf with a tenth of the Sun's mass will continue burning fuel for 10 trillion years.

• ${\boxed{\red{\text{What if the sun was a red dwarf?}}}}$

⇒ Red dwarfs stars are smaller and cooler than our relatively average star, the Sun. ... We think that many red dwarf star systems may have habitable, Earth-like planets that orbit them but replacing our Sun with a red dwarf would be rather disruptive to our Solar System and home planet.
