1 The smallest, feeblest stars, called M5 red dwarfs, have about 5 percent of the mass of our Sun.

2 But eventually, even red dwarfs will shrivel up and die.

3 It orbits a red dwarf star.

4 Kirkpatrick doesn't think Nemesis will be the red dwarf star with an enormous orbit described by Muller.

5 What they revealed is a planet circling the red dwarf star, Gliese 581.

6 The rising red dwarf star shows expected stellar magnetic activity which includes dramatic and violent prominences.

7 That's because Gliese 581 is a red dwarf — a pipsqueak of a star compared to our sun.

8 Even for a red dwarf star, this is probably too close to be habitable.

9 The third star, a red dwarf called Proxima Centauri, circles this couple at a considerable distance and is too faint for Fischer's team to study, but it could boast small planets, too.

10 He thinks Nemesis is a red dwarf star 1.5 light years away.

11 They found faint signatures of these red dwarf stars in eight massive elliptical galaxies relatively close to us—between 50 million and 300 million light-years away.

12 Gliese 581 is a red dwarf star 20.5 light-years from Earth.

13 Classified as a red dwarf, the star is much smaller and colder than the Sun.

14 It orbits a red dwarf star about 28, 000 light-years away, making it the most distant exoplanet currently known.

15 The discovery that elliptical galaxies have many more red dwarf stars than the Milky Way means that the universe might have three times as many total stars as previously thought.

16 Red dwarf stars, which are by far the most common stars in our galaxy, were once considered unlikely places to find Earth-like planets, but new studies contradict that view.

17 This might be an exaggeration, though, because astronomers believe this planet would have to be 80 times as massive to ignite into a star. Even at that, it'd be a red dwarf star.

18 This allowed the host star to be identified as a red dwarf star located 19,000 light-years away.

19 If astronomers get lucky, Webb will be able to study a nearby super-Earth orbiting a red dwarf star.

20 At the other end of the wetness scale, planet GJ 1214b, which orbits a red dwarf star, may be almost entirely water.

21 Planet G was the sixth planet found circling Gliese 581, a red dwarf star 20 light-years from Earth.

22 Plants that relied at times mostly on the dim red dwarf might need light from all across the visible spectrum.

23 The most common type of star in the galaxy is the humble red dwarf.

24 The two stars are so close together that the red dwarf cannot hold itself together and loses mass to its companion.

25 Or a planet with two stars may have one sun-like star, along with a red dwarf star that's also common in multi-star systems.

26 Moreover, given ingenious mission design,[] it might be possible to visit the nearby red dwarf star Proxima Centauri as well.

27 His fame has led to guest roles in The Simpsons, Star Trek: The Next Generation and Red Dwarf.

28 The star is located 20 light-years from Earth in the constellation Libra. Red dwarf stars are about 50 times dimmer than our sun.

29 Gliese 581g is one of two new worlds the team discovered orbiting the red dwarf star Gliese 581, bumping that nearby star's family of planets to six.

30 None of those planets are like Gliese 581 g, a rocky world about three times the mass of Earth orbiting -- along with five sibling planets -- a red dwarf star 20 light-year from Earth.

31 That's what a French team did for the planet Gliese 581d, which orbits a red dwarf star about 20 light-years from Earth.

32 The red dwarf star Ross 154 looks as if it's been relegated to the position of "eighth closest star."

33 These are epsilon Eridani, a single K star at a distance of 10.5 light-years, and the red dwarf GJ 674 at a distance of 14.8 light-years.
