As it orbits its star so close, it is … "In other words, they are much closer to their (parent) star than the Earth is to the Sun," Ribas said. It is a red dwarf in the direction of the constellation of Aries. If they’re confirmed, both of the newly spotted worlds are nearly identical to Earth in mass, and both planets are in orbits that could allow liquid water to trickle and puddle on their surfaces. What scientists are excited about is that both exoplanets are excellent candidates to support life, alongside Proxima, which to date was the planet that presented the best conditions for habitability. Meanwhile, recent graduate Tim Riggins (Taylor Kitsch) struggles with his plans for the future. Teegarden hovers in the midst of a habitable zone, which means the temperature on its surface is between 0 degree Celcius and 100 degree Celcius, meaning it could very well have water on surface. The planet's minimum mass is 1.05 Earth masses (M⊕); this value would be the true mass if the planet's orbit is not inclined from the Earth's perspective. Teegarden c, on the other hand, sits farther out, and has a surface temperature more like Mars, sitting at roughly -47°C. The Teegarden star system is the 24th nearest star system to ours, and the fourth closest among those systems with exoplanets. Teegarden b zips around its host star in only five days and is only 5 percent more massive than Earth. … Two planets only slightly more massive than our own world have been discovered orbiting Teegarden’s Star, a red dwarf just 12.5 light years from Earth.
