Planet hunting – TOI 270

In the search for planets and the habitability of planets we discover interesting solar systems. Let us take a look at TOI 270.

The star is a red dwarf, cooler in temperature then our own sun and has a longer lifespan then our sun. And red dwarf stars emit relatively little light. Its solar flares can be a problem for the evolution of life on its planets.

TOI-270 hosting a system of 3 known planets. It’s discovery announced in 2019.

TOI-270 is a red dwarf star 73.3 light-years (22.5 parsecs) away in the constellation Pictor. It has about 39% the mass and 38% the radius of the Sun, and a temperature of about 3,506 K (3,233 °C; 5,851 °F).

TOI-270 b is a super Earth exoplanet. Its mass is 1.58 Earths, it takes 3.4 days to complete one orbit of its star, and is 0.03197 AU from its star.

TOI-270 c is a Neptune-like exoplanet. Its mass is 6.15 Earths, it takes 5.7 days to complete one orbit of its star, and is 0.04526 AU from its star.

TOI-270 d is a Neptune-like exoplanet. Its mass is 4.78 Earths, it takes 11.4 days to complete one orbit of its star, and is 0.0721 AU from its star.

This discovery is so cool. And it is asking for more research.
