10 Reasons Why Moons of Rogue Exoplanets Might Be a Good Place For Alien Life

By: April Carson

A massive rogue exoplanet that left its home stellar system was the subject of a study by scientists. They took into account the mass of bodies, their orbits, chemical composition, and chemical evolution over ten million years in their analysis. The calculation revealed that a significant quantity of water may exist on the satellite if certain criteria are met; however, it may be difficult for life to exist.

Planets can alter their orbit throughout their existence. In general, this is caused by interactions with other massive bodies, planets, or companion stars of the parent star.

For example, the unusual chemical make-up of Mars may be explained by a similar situation: some researchers propose that it formed in the region of the main asteroid belt and only then migrated to its present position as a result of Jupiter's gravitational pull.

If the interaction between two bodies is stronger, their orbits may break apart and the planet will fly away from the star system into outer space, becoming an orphan planet.

It may appear that the circumstances on such rogue exoplanets or their satellites will be as cold as possible, since a body without a star is destined to freeze. This isn't always the case, at least for these planets' satellite.

The solar system's largest planet, Jupiter, has at least four small moons. These astronomers found that the heat coming from within the planet was sufficient to melt these ice balls. The inner heating of Saturn's satellites is caused by friction as they orbit, which melts the ice balls.

The decay of radioactive elements that are incorporated in the nucleus adds to the overall heat generated. As a consequence, there is an under-ice ocean beneath Europa, Enceladus, and a number of other satellites.

Everything you need to know about the possible presence of water on moons orbiting rogue exoplanets

1. Patricio Ávila and his colleagues from the University of Concepción conducted computer modeling and determined under what conditions a satellite's orphan planet might have water on its surface.

2. The first thing to consider is that the planet's system and the satellite must be stable in order for the planet to have a significant mass. The satellite must revolve around a huge body and orbit about an elongated orbit in order for strong tidal heating to be effective.

3. Scientists opted for rogue exoplanets with a mass of Jupiter and a satellite of Earth-like mass that orbits around them in an elliptical orbit with an eccentricity ranging from 0.001 to 0.5, according to the UPLIFT technique.

4. Furthermore, the greenhouse effect is required to keep the heat. The Patmo algorithm, which calculates the relationship between the atmosphere and electromagnetic radiation along a straight line and considers several variables, such as photochemical reactions taking place in gas, was used by researchers to determine the needed amount of opacity.

5. Finally, the formation of water necessitates a particular chemical composition in the planetary body. Scientists assumed that the satellite's atmosphere is 90% carbon dioxide and 10% hydrogen in all of the scenarios considered.

6. Cosmic rays, which will break down CO 2 in such a condition, will be the dominant force driving chemical reactions. The CO + O carbon is next broken down by cosmic rays. Then oxygen is released; however, under the influence of cosmic rays, water will decompose into OH + H.

7. The researchers utilized a simulator to calculate the chemical evolution of the atmosphere on the rogue exoplanet's satellite and equilibrium points of various chemical processes.

8. Water is formed both at a relatively low atmospheric pressure and at a considerably higher one, about 10 bars. In the long run, variations in cosmic radiation intensity are practically inconsequential.

9. In a scenario with little water for 10 million years, relatively little water is generated: one hundred thousand trillion tons, which is tens of thousands of times less than the Earth's hydrosphere. In the high-pressure condition, about 13 times more water is produced.

10. According to experts, a celestial body like this may be described as "relatively viable" – far worse than Earth but better than Mars. The rogue planet's satellite's orbit will shrink over time, and the surface temperature will drop below the melting point of water because of insufficient tidal heating. Only the presence of additional moons can extend this timeframe.
