9 gru 2023 · The two small moons of Mars, Phobos (about 22km in diameter) and Deimos (about 13km in diameter), have been puzzling scientists for decades, with their origin remaining a matter of debate.
Mars' moons are among the smallest in the solar system. Phobos is a bit larger than Deimos, and orbits only 3,700 miles (6,000 kilometers) above the Martian surface. No known moon orbits closer to its planet. It whips around Mars three times a day, while the more distant Deimos takes 30 hours for each orbit.
17 lut 2023 · Since arriving at Jezero Crater in 2021, the six-wheeled, nuclear-powered rover has been examining geologic features and collecting samples of the Red Planet that are central to the first step of the NASA-ESA (European Space Agency) Mars Sample Return campaign.
Like Earth, Mars has distinct seasons, but they last longer than seasons here on Earth since Mars takes longer to orbit the Sun (because it's farther away). And while here on Earth the seasons are evenly spread over the year, lasting 3 months (or one quarter of a year), on Mars the seasons vary in length because of Mars' elliptical, egg-shaped ...
Moons of Mars. Mars has two moons, Phobos and Deimos. Both are thought to be captured asteroids, or debris from early in the formation of our solar system. Phobos is the larger of Mars' two moons. It orbits Mars three times a day, and is so close to the planet's surface that in some locations on Mars it cannot always be seen.
1 dzień temu · Like Earth, Mars has clouds, winds, a roughly 24-hour day, seasonal weather patterns, polar ice caps, volcanoes, canyons, and other familiar features. There are intriguing clues that billions of years ago Mars was even more Earth-like than today, with a denser, warmer atmosphere and much more water — rivers , lakes , flood channels, and ...
2 maj 2023 · Where did the moons of Mars come from? That’s a question scientists still can’t answer. We know that Earth’s moon was likely formed from a giant impact on our planet about 4.5 billion years...
