Crazy they just now found it.
Its brightness magnitude is expected to be -16. In comparison, the sun has a magnitude of -26, and Comet Hale-Bopp was magnitude -1
Why is it crazy they just found it care to explain your logic on that![]()
Because a large portion of the objects in the oort cloud is cataloged and tracked, just for this reason.
It's also rare that we get such a big, close comet thats gunna make its first pass close to the sun.
I think you may be getting confused with the asteroid belt. Even in the Kuiper belt very little is catalogued and tracked. No objects in the Oort cloud have been observed or tracked as it begins a vast distance away... Well on the way to Proxima Centauri in fact! Bearing in mind that comets are very small and dark, there is no way of detecting them until they move well into the Solar System and begin to reflect the Sun's light.
Here's a great article... It may be a Wiki page, but it's well written and well referenced...
