I have a planet orbiting a red dwarf and, as expected, it is tidally locked to its star. I know that these planets will have a very significant temperature difference between the diurnal and noctur...
I am creating a planet with an orange dwarf as its host star and which is at a certain distance from it in such a way that it receives 1 % of the light received by the Earth from the Sun. Obviously...
My idea is a carbon planet 50 % larger than Earth and with 5 times its mass (approximately), but I set these values "‹"‹after investigating those of several discovered exoplanets and none of them i...
I am creating a carbon planet with seas of methanol on its surface, but I am not sure that this is possible. It is predicted that carbon planets are depleted of water, since the available oxygen w...
Consider a planet very similar to Earth, with the same radius and the same mass. In a very simplified model of its interior, 70 % of its mass is magnesium silicate and the remaining 30 % is iron. T...
Consider a planet $P$ of radius $r$ larger than Earth, whose mass is $r^3$. By the square"“cube law, this planet will have the same density as the Earth... assuming that the gravitational compressi...
My idea is a planet that orbits a red dwarf at a distance in which the apparent magnitude of this seen from the planet is the same as that of the sun seen from Earth. Does this mean that the daylig...
My planet (I'll call it $P$ for practical reasons) is 2 AU from the Sun, a distance in which it receives 25 % of the sunlight that Earth receives. This can be estimated with the Inverse Square Law:...
I have a planet covered with a large shallow ocean, which extends over most of its surface. I want to turn this planet into a great desert, specifically a salty desert (the salts of this desert are...
Magnetic white dwarfs (MWD) comprise almost 2 % of all white dwarfs and they are characterized by having a strong magnetic field, whose strength varies between 1 T and 100 kT. Compared to the Earth...
Consider a planet with life forms, which are different than those found here on Earth, orbiting a star similar to the Sun. Such life forms don't use oxygen and, therefore, the planet's atmosphere i...
Can a planet with a dense atmosphere composed mainly of sulfur dioxide have a blue sky like Earth's due to Rayleigh scattering? Or would the composition change the color of the sky? I mean, it's we...
