We May Have Had an Interstellar Visitor for Eons and Scientists Are Stumped

The origins of Comet 96P/Machholz (96P) have puzzled scientists for decades since its discovery. It is a four-mile-wide “sungrazer” object with a host of weird properties that suggest it may be an interloper from another star system. For instance, 96P’s composition is extremely unique and its orbit is highly tilted, causing it to pass closer to the Sun than almost any other comet.

These features, among others, suggest that 96P may have been rerouted into our solar system by a chance encounter with Jupiter after its voyage across interstellar space. In an ironic twist, however, the comet's interactions with Jupiter have obscured its backstory and raised the possibility that its oddities could simply point to an origin in an unusual part of our own solar system, or as part of a local celestial body that broke apart.

96P was first discovered by the amateur astronomer Donald Machholz, who spotted it with binoculars from California in 1986. More recent observations have revealed that the object is bizarrely depleted in common materials, like carbon and cyanogen, and does not appear to possess the dusty atmosphere, or “coma,” seen around other comets in the solar system.

These features hint that the comet might be a completely stripped down nucleus with a “primordial and possibly…interstellar origin,” according to a 2019 study in Astrophysical Journal, co-authored by Knight, that was based on observations of 96P’s 2017 perihelion.

Those observations also revealed that the comet’s colors appear similar to those of ‘Oumuamua, which was the first unambiguous interstellar object ever seen in the solar system. ‘Oumuamua hurtled through our system in late 2017, and also displayed weird features and motions that led to some speculation that it was a piece of alien technology, though most scientists think it had a natural origin

Idiots who are trying to explain something that they don’t know anything about to get clicks on their internet links.

Scientists are stumped about possible alien visitors? Oh, for goodness sake!
All they have to do is pick up a copy of ‘Weekly World News”.

Oumuamua, which was the first unambiguous interstellar object ever seen in the solar system.

Close enough.

Slim Whitman actually was very talented and I still enjoy his music.

Here is his version of Indian Love Call that was featured in the 1996 movie, Mars Attacks!

It is a classic. Sorry for hijacking the thread.

Donald Machholz, comet hunter and co-inventor of Messier marathon, dies at age 69
Soft-spoken with an encyclopedic knowledge of the solar system’s small bodies, Machholz regularly scoured the heavens for most of his life.

But call them angels or demons or God or Jesus and watch what happens.

“the object is bizarrely depleted in common materials, like carbon”

See? Carbon taxes work!
