In the future, humans should make an attempt to live on another world. However, finding one that we can get to is another process.
Recently, the NASA Transiting Exoplanet Survey (TESS) Satellite found a new potentially habitable exoplanet. The planet is about 1.2 times the size of earth, and orbits another star every 37 days.
The planet, which is called TOI 700 d, is a candidate for being habitable. It has a good orbit distance, which suggests that liquid water could be stable. Scientists also ran 20 different simulations, which suggests the planet is rocky. However, there’s a small chance it could a gas planet – which we probably couldn’t survive on.
It’s about 101.5 light-years from earth. This means it’s much easier for us to view it with large telescopes.
The Transiting Exoplanet Survey Satellite (TESS) finds worlds using the “Transit method”, which looks for changes in stellar brightness. This change is caused when orbiting worlds cross other stars. This same procedure has also helped find many other exoplanets.
