Out of these seven planets, Trappist-1e has the best chance of being habitable.
All of Trappist-1’s seven planets have rocky surfaces like Earth and almost all have water in vapor, liquid, or solid form, which make humans look for opportunities to settle there. Located about 40 light-years from Earth, its star Trappist-1 is a red dwarf star that weighs 0.09 times the Sun’s mass. However, because the planet is very close to Earth, it might be the first exoplanet for humans to visit, so we should keep it in mind.Īnother example of an exoplanet in the Goldilocks zone is Trappist-1e. As of now, we are unsure of whether the planet is rocky, icy, or gaseous. Also, as the planet might be tidally locked to its star, meaning that the same side faces the star at all times, one side might be boiling and the other extremely cold. For one, Proxima Centauri B suffers from overwhelming stellar wind pressures from its star. Although Proxima Centauri B lies in the habitable zone and could have an atmosphere and liquid water, there are obstacles that make it harder for people to settle there. Proxima Centauri is a red dwarf star that is the closest star to our sun by a distance of 4.2 light-years. One example of an exoplanet that suits the Goldilocks principle is Proxima Centauri B.
We can’t be sure yet, but some might even have life. The only habitable planet orbiting the Sun is Earth, but there could be thousands of other exoplanets in the universe that have the conditions for liquid water. In our solar system, the Goldilocks zone is a doughnut-shaped area between Venus and Mars’s orbit, with our earth in the middle. The Goldilocks zone (or habitable zone) is a space shaped like a doughnut around a star, where the temperature is “just right” for water to remain liquid, signaling the potential for life. Interestingly, there is also a principle called the “Goldilocks zone” in astrobiology. She finds that the first one is too hot, the second one too cold, and the third one is just right. Have you ever heard of the story of Goldilocks and the Three Bears? In the story, Goldilocks sneaks into a bear family’s house and comes across three bowls of porridge.
