What star does HD 40307 g orbit?
What star does HD 40307 g orbit?
K-type star
HD 40307 g is a Neptune-like exoplanet that orbits a K-type star. Its mass is 7.1 Earths, it takes 197.8 days to complete one orbit of its star, and is 0.6 AU from its star. Its discovery was announced in 2013.
Is HD 40307 habitable?
The planet orbits at a distance of 55.8 million miles (90 million kilometers) from the star. This distance puts it into HD 40307’s habitable zone, the region in a planetary system where liquid water can exist on a planet’s surface. The planets Earth and Mars orbit within our sun’s habitable zone.
How was HD 40307 g discovered?
The planet was discovered by the radial velocity method, using the European Southern Observatory’s HARPS apparatus by a team of astronomers led by Mikko Tuomi at the University of Hertfordshire and Guillem Anglada-Escude of the University of Göttingen, Germany.
Where is HD 40307 located?
HD 40307 is an orange (K-type) main-sequence star located approximately 42 light-years away in the constellation of Pictor (the Easel), taking its primary name from its Henry Draper Catalogue designation. It is calculated to be slightly less massive than the Sun.
Do exoplanets orbit our Sun?
The Short Answer: All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets.
Can we live in super-Earth?
To live on a Super Earth would require super strength. If Earth were 10 times larger, gravity would be 10 times stronger. This is based on the formula of Surface Area = Mass/Radius squared. A short jog on a Super Earth would feel like running a marathon!
What planets have drinkable water?
Evidence points to oceans on other planets and moons, even within our own solar system. But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. In our solar system, Earth orbits around the sun in an area called the habitable zone.
