I read that the New Horizon spacecraft passed by the Ultima Thule. I also got to know that it is a flat, snowman-shaped rock.

What is so special about it?

    $\begingroup$ What's your prior research? Did you read the wikipedia page on Ultima Thule / New Horizons? $\endgroup$ Commented Feb 19, 2019 at 17:26

    $\begingroup$ Hello, Please take the tour. By research we mean that you can ask a better question if you try find out about it first. You should read the wikipedia page first. It will make your question better. You have done research already because you know "that it is flat". Learning that is "research". $\endgroup$

  • Ultima Thule is the first small Kuiper Belt Object (KBO) we have visited. For the first time, we can see a KBO as more than a tiny point of light in a telescope.
  • it seems to be flat, rather than roughly round. This is really unusual (we've never seen that shape before in planets, moons, asteroids etc.).
