Content: Furthermore, if life on the planet is to be given a chance to evolve, certain other conditions have to be met in its rotational motion. For example, there should be some axial tilt perpendicular to its orbit, which will result in seasons on the planet or celestial object. A Molten Core
To sustain any type of life, a planet requires a rapidly rotating magnetic field to protect it from flares from nearby stars. This is what we call the core of the planet. A planetary core is a terrific source of geothermal energy, allows the cycling of raw materials, and spawns a magnetic field around the planet to protect it from harmful radiation. It should be noted that Mars was known to have a liquid core at one time, but its heat dissipated quickly because Mars is a smaller planet. Holding an Atmosphere
Earth’s atmosphere not only fulfills our most basic needs of providing oxygen but also keeps the planet warm by trapping carbon dioxide and other gases. It also protects life on the planet by blocking the vast majority of harmful radiation. Therefore, any habitable planet must have all the necessary conditions in place to have an atmosphere or at least a protective layer of essential gases. As stated earlier, since we do not know of the existence of any life outside of Earth, these assumptions are deduced from the particular conditions that support life on Earth.
