A comet looping behind the sun right now could emerge this fall as a once-in-a-lifetime spectacle that shines in the sky so brightly, it is visible with the naked eye around the world - if it survives.

Interesting article.

Despite the article statement the brightness of the comet following a perihelion breakup would likely be brighter rather than fainter than a model brightening curve of an intact comet.

The brighter result is likely due to a breakup exposing fresh ice along the fracture planes which would immediately sublime under the impressive insolation rate @ perihelion.

I would prefer to see a breakup, but as it has been around before, in orbit it is likely a relatively tough fragment of the sungrazer comet family.

Of note there is a REAL sungrazer comet family, all arriving from much the same direction and exiting in much the same direction spread over an interval of time of at least 4 centuries. This family appears to be the scattered orbital results of a big object that broke up in a past perihelion pass.

Have a nice day: Ag
