Are there yet any credible theories for why we see so few of these? AIUI, if we're correct about how planets form, there should be far more of these than we're seeing. Is it that we're probably wrong about how planets form, or there's something strange about our part of the galaxy, something else or do we just have no clue?
- dr_zoidberg 9y agoThe general consensus amongst astronomers is that these objects are far too faint to be seen. As more sensitive instruments are developed/deployed, we should begin seeing more of them.
- Voloskaya 9y agoEstimate is that there might be about ~10 of these object passing through every year, so it's not a lot to start with. In addition asteroids are relatively small and hard to spot since they are inert. We managed to spot this one because we were lucky it came so close to earth.
