It's probably not going to strike but all of them are capable of doing so in time....see the Moon. Craters everywhere. There are craters on Earth too but most disrupted by erosion, and plate tectonics. The Earth cannibalises its own crust this destroying evidence of most impacts except on very old cratons, but the Moon has preserved its craters because the only erosion is space weather, and of course meteorite flux which after a while overprints impacts like rain on a pavement eventually washes out all the raindrops. There was thought to be flood basalt eruptions about 3 Billion years ago on the Moon which are the dark (mare-seas) you see on the Moon's surface and they are relatively flat. The far side of the moon lacks these flood basalts, and that's quite interesting. Why? Why does the far side of the moon differ from the near side? This is a very important point for blue mooners.
The Moon contains secrets to the Earth's past which is why we must go back, and indeed we are. Though whether we need human's on the moon I don't know. In 2024, the US plans to send a woman on to the surface of the Moon. The Chinese are there now, at the Lunar South Pole (robots -not people), the site of possibly the biggest impact basin in the solar system - hidden from us because it's on the SOuth Pole / far side. Known to lunar scientists as the South pole aitken basin. Important as lunar mantle maybe exposed on the moon's surface. The Lunar poles are thought to contain water ice, and are amongst the coldest places in the Solar system - reason being that the Moon (unlike the Earth) rotates on an axis which is almost exactly perpendicular to the plane of is orbit, so the craters are permanently exposed to the the deep cold of space. Water ice may fuel the journey to Mars - hydrogen, and it maybe possible to grow plants on the Moon. I believe the Chinese have grown a seedling on the Moon.
