Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the stellar type?M-type main-sequence star (Red Dwarf)
2. What is the surface temperature?Typically 2,000 K to 3,700 K
3. What kind of star is GS-NDG-9422?GS-NDG-9422 is a red dwarf, a small M‑type star that is much cooler and dimmer than the Sun. It has a mass between 0.08 and 0.6 times the Sun’s mass and a surface temperature of about 2,000 to 3,700 Kelvin.
4. How does GS-NDG-9422 produce its light?It fuses hydrogen into helium through the proton‑proton chain, a slow reaction that lets the star shine for hundreds of billions to trillions of years.

Main Sequence Star: A star that is fusing hydrogen into helium in its core, representing the longest and most stable phase of a star's life.
Proton-Proton Chain Reaction: The primary nuclear fusion process in low-mass stars where hydrogen nuclei (protons) combine to form helium.
Tidally Locked: Describes a celestial body that rotates at the same rate that it orbits its primary, resulting in one side always facing the primary.
