TOI 700 e has been confirmed orbiting inside the habitable zone of its star, TOI 700. TOI 700 is a small, cool star (known as an M dwarf star), located around 100 light-years away from us in the Dorado constellation.
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.
Once a star left the gravitational embrace of its solar system, its pretty much destined to drift through interstellar space forever. Astronomers call these drifters “rogue planets” and one of them have been found recently.
Researchers have found an Earth-size exoplanet with a pi-like 3.14-day period. Whirling around its star at some 291,000 kph, the planet’s surface temperature is estimated at around 176 degrees Celsius.
A new statistical analysis shows Earth-size planets are likely orbiting one in six Sun-like stars. The study is the most accurate estimate yet, researchers say, of the potential population of roughly Earth-size worlds in the Milky Way.
Scientists working with data from the Kepler mission have discovered an additional 18 Earth-sized worlds. Among the 18 is the smallest exoplanet ever found.
