    I’ve read like eight of these articles about this Moon just trying to find out if we can see it without a telescope.

    I’m assuming we can’t see it, but none of the articles I’ve read mention it. it seems crazy that none of them mention its visibility.

    Will we be able to see the second moon?

        If we send rocket(s) up and can fiddle with its velocity enough, we could keep it.

        I feel like if you capture a new moon, you should also get to name it.

        If McDonalds will sponsor it, we could have Luna and 98 Big Macs.

    An asteroid called 2020 CD3 was bound to Earth for several years before leaving the planet’s orbit in 2020

    How can something that’s in an orbit for years then just leave again?
    Is the orbit so big it crosses other planets’ sphere of influence?
    Or is its apoapsis far enough away for the sun to snatch it away?

      Gravitational interactions between Earth, Moon, Sun leading to the orbit never really being stable, probably. The asteroid decided Earth orbit wasn’t its’ forever home.

        Its also very hard to get an object into the perfect orbit that it wont float away. Our moon is slowly drifting farther and farther from us

    spinning around Earth in a horseshoe shape for about two months

    what? what kind of orbit is that?
