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...
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...
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...
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 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...
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:...
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...
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...
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...
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...
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 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...
