The asteroid was discovered in August and is set to become a mini-moon, spinning around Earth in a horseshoe shape for about two months.

    A second mini moon? Do we even have a first mini moon?

    spinning around Earth in a horseshoe shape for about two months

    what? what kind of orbit is that?

      It’s a parabola or hyperbola. Of course, it’s not technically an “orbit” since it isn’t closed; the Wikipedia pages are called Parabolic trajectory and Hyperbolic trajectory.

      The kind that takes more than 2 months to ‘complete’. From the perspective of the earth it makes a horseshoe shape. From the ‘temporary moon’ perspective it gets a trajectory adjustment on its solar orbit.

      It’s more like a gravity assist that takes 2 months to complete than an orbit.

    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?

      The posted article says no, not even with an amateur telescope

        of course i skim this one and it’s in the final paragraph.

        thank you!

      The closest approach is about 600,000 Km away. That’s more than twice the distance to the moon. At that distance, to be (just barely) visible to the naked eye, it would have to be about 170km across, which would put it among the largest asteroids in the solar system. In fact, 2024 PT5 is only about 11m across (~36ft). You would need quite a powerful telescope, indeed, to see an object that small at that distance.

    Was wondering about its size: 11 meters (36 ft) in diameter per wikipedia

        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.

    So if I’m doing the math right… that’s 3 total moons:

    Moon

    Mini moon 1

    The second mini moon

    Science is fun.

    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?

        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
