By a stable orbit I mean not getting ejected by the other planets or ejecting them, Let's create a scenario where Neptune occupies an orbit in the asteroid belt at 2.76 AU, Ceres average distance f...
What orbital parameters could I give seven Mars/Earth sized planets so they have stable orbits around a G-type star like The Sun, they need to fit between 0.5 AU and 1.7 AU.
Let's use Mercury as an example, we can pretend it orbits in the habitable zone of the Sun, would Mercury's magnetic field be able to protect an Earth like atmosphere? And would the lower gravity m...
Would it be easier to build Skyscrapers on a planet with 50% of Earth's gravity, and the same atmospheric pressure of the Earth. I noticed someone asked why the planet has lower gravity, this is be...
An alien race wants to test out its new technology that modifies the atmosphere of Earth and other terrestrial planets, they decide to center it over Central Park, NYC. One of the first things they...
I want to create a terrestrial planet with a very long lasting hurricane similar to the great red spot, I assume the planet will have to be covered by ocean. Could there still be some small islands...
What conditions might make a planet more likely to develop silion based life, the factors I need to kmow are listed below Temperature of the planet The solvent that they can use in their biology ...
I am creating a race of aliens that are amphibious and mammalian in detail, they have six tentacles, bunny ears and also fur covering their bodies. They are about 3-4 ft in length, if this species ...
Some information about their homeworld: Their homeworld, 0.34247 (M⊕) 0.54 G, 10156 km. The atmospheric pressure of their homeworld is 62% of the Earth's, and the planet has an average temper...
My question is pretty simple, all the details about the planet are pictured below.
Some details about the planet and its moon plus the host star. Star: 0.85 Sol, 0.54% of the Sun's luminosity Planet: 0.04926 (M⊕) 4836 km, 0.34 G, Orbits the host star at 0.901 AU. The atmosph...
By Mars sized I mean with masses between 0.10 (M⊕) and 0.25 (M⊕), the planets need to have independent orbits around the star. We can assume the habitable zone stretches from 0.70 AU, to 1.5 A...
I'm trying to create a habitable planet but with a low atmospheric pressure, similar to Mars. But instead with 15 percent of Earth's atmospheric pressure, what traits can I give my animals so they ...
Lets say there's a super earth orbiting the sun at 3.00 AU, how thick would its atmosphere have to be to trap enough heat to make the planet warm enough for liquid water to flow on its surface?
The planet is a Super-Earth with 1.839 Earth masses and an average surface temperature of 180.7 degrees farrenheight, the atmospheric pressure is 50 times more dense than Earth's and there's large ...
I was wondering what is the smallest a terrestrial planet can be and maintain plate tectonics and generate a magnetic field, atleast to Earth's current age?
I was wondering if a planet that has a higher escape velocity but lower surface gravity lose its atmosphere more faster/slower than a planet that has a higher surface gravity but lower escape veloc...
I was just wondering if it would be possible for a planet to have life that only uses noble gases in their biology. Like for example breathing in certain noble gases like Argon or Krypton for ener...
If we assume their homeworld is similar to Titan, but instead orbiting a Neptune sized gas giant and a bit bigger and receiving the same amount of Solar energy as Titan, The star is a main sequence...
For my story I am working on, a peaceful alien race that is studying Earth wants to terraform the Moon by building a giant sealed dome over its entire surface, then they will create forests, desert...
Would it be possible for a terrestrial planet say atleast >0.3 Earth masses orbiting in the L3/L4/L5 and L1/L2 Lagrangian points of a Jupiter sized planet in the habitable zone of a Sun-like sta...
Would it be possible for a moon that receives a lot of tidal heating from its gas giant parent planet like Io to develop intelligent life? Assuming moon is big enough to support an atmosphere and i...
I just wanted to know something relatively simple. What evolutionary factors could lead to an alien prey species to develop human like intelligence, and by prey species I mean a species like bunnies.
I am creating a hypothetical race of aliens native to a planet orbiting an F class star; the mass of the star is 1.50 (M☉). Would this star live long enough to allow the evolution of intelligent ...
What are some possible ways this could happen?
