乐生活Phobos, orbiting Mars in a very close orbit, is only about 6,000 kilometers from the surface of Mars, and is gradually approaching. One day (about 20 million to 40 million years later), Phobos will be too close to Mars and may be torn apart by its gravitational tides, becoming a halo of Mars, or hitting the surface of Mars altogether. Although it’s a sad story, Wondering Planet’s cartoons are really budding!
