The theoretical Roche limit is different for rigid and fluid bodies. If Phobos were a fluid body, it would already have passed the Roche limit at 10500km. This is because fluid bodies will deform into an ellipse pointing towards the planet, and this amplifies the tidal forces and so causes ...
What does a Solar Eclipse Look Like on Mars?
Web30 nov. 2024 · The orbit of Phobos is not perfectly circular though, so at periapsis (9,234km) and apoapsis (9,518km), the corresponding angles are 43.1 ° and 41.7 ° (More than a fifth but less than a fourth of the sky). By comparison, the Moon as viewed from Earth is about 0.52 ° in diameter. With an altitude of 5,989 km (3,721 mi), Phobos orbits Mars below the synchronous orbit radius, meaning that it moves around Mars faster than Mars itself rotates.
