Theories Behind Phobos and Deimos’ Origins
Two major theories have dominated the dialogue on how these moons shaped. One posits that they’re asteroids captured by Mars’ gravitational pull. However, this speculation fails to account for his or her steady, near-circular orbits. The second idea means that Phobos and Deimos might have shaped from particles after an enormous collision involving Mars. Jacob Kegerreis, a planetary scientist at NASA’s Ames Research Center, believes a hybrid situation might present a believable reply.
Kegerreis and his crew suggest that an asteroid might have been captured by Mars’ gravity however was then torn aside, creating a hoop of particles. Over time, this materials might have coalesced to kind the moons, inheriting the round orbits noticed right now.
Simulations Offer New Insights
Hundreds of supercomputer simulations have been performed to check the speculation. By various the asteroid’s measurement, velocity, and spin, researchers observed that rings of particles constantly shaped underneath sure situations. Kegerreis defined that they noticed materials able to forming a disk throughout totally different situations.
Upcoming Mission to Provide Answers
The Japan Aerospace Exploration Agency’s Mars Moons Exploration mission, set for launch in 2026, goals to assemble materials from Phobos. This evaluation might decide whether or not the moons share a composition with Mars, supporting the collision idea, or resemble asteroids with water-rich compounds, backing the shredded asteroid speculation.
Findings from this mission might make clear Mars’ moons and assist perceive moon formation round exoplanets, broadening our understanding of planetary techniques.
