The planet, nearly 10 times Earth’s mass, orbits a small, red-orange star about 200 light-years away. This planet is extremely hot, with an estimated temperature of 1,050 Celsius.
While observing the star system HD 23472 , researchers found three super-Earths and two super-Mercuries. This type last of exoplanet is still very rare—counting these two, there are only eight known super-Mercuries.
The astronomers underlined that the star, these planets are orbiting is the second-coolest star found to host planets after TRAPPIST-1. They added that their finding is the second-most favorable habitable-zone terrestrial planet known so far.
It's called TOI-1452b, and measurements of its size and mass suggest a density profile consistent with a global liquid ocean. An exoplanet is just 100 light-years from Earth
Astronomers and geologists have recently concluded that most rocky planets orbiting nearby stars are more diverse and exotic than previously thought, with types of rocks not found anywhere in our Solar System.
A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth.
Recently, an international team of scientists, combined data from Kepler Space Telescope and Gaia Observatory revealed is that half of the Sun-like stars in our Universe could have rocky, potentially-habitable planets.
An Earth-like world is one that’s rocky and that orbits a Sun-like, or G-Type, star. The Milky Way has 400 billion stars, with 7 % of them being G-type, meaning that less than six billion stars may have Earth-like planets in our Galaxy.
Astronomers have found an exoplanet more than twice the size of Earth to be potentially habitable, opening the search for life to planets significantly larger than Earth but smaller than Neptune.
