It's still an awesomely important discovery.

Does anyone have a theory on how this object got its speed? That's incredibly fast. What's the speed of Voyager 1 and 2?

Going on a limb here, but IF it is a probe, maybe the designers make it shut down during travel (tumbles because who cares or to keep it camouflaged as a asteroid) then wakes up when it nears planets of interest?

I don't know but I find this object pretty interesting.


If it has traveled through the galaxy, then it could have been accelerated by the gravitational pull of stars. Perhaps it was ejected during a collision between two planets or when a star went supernova. Imagine a blob of metal being ejected by a exploding stellar core, then cooling down when in contact by surrounding gas clouds.

According to theorists:


It has been hopping from one solar system to another for millions of years.


Which might mean it is traveling too fast to be trapped by a typical solar system gravity well.

Waiting for more clues, you would think they would have done an analysis of the density that might hint at its origin.
They believe the Earths moon was the result of an early collision, the moon being too massive to reach escape velocity.
All I've heard so far is that this asteroid does not reflect more than 6% of the probing radiation.

Density requires knowledge of mass and volume, neither of which is even remotely known.

Its discovery wasn't an accident. new search programs were recently established for potential Earth-threat objects, and statistically about one of these non-local objects ought to be spotted every year.

Note that the discovery was quickly announced and speculations soared openly. That's the real non-conspiratorial world.

The object only reflects 4% of radiation in the sunlight spectral range.
Some estimates seem to indicate a half mile long squirt with only an 80 meter cross section.
If the orbital path was tracked with sufficient accuracy the mass should be known.
I don't see anything conspiracy worthy yet unless there is something hidden in the observational statistics.
Reports vary so much it would be difficult for anyone to form much of a scientific opinion.

How?

How?

By measuring the deflection from a straight-line path (caused by the Sun's gravity) as it passed.

Any "probe" will likely be nano in size. It's just more efficient. It's important to segregate the drama-based themes of TV shows from a practical reality, though it's compelling to suspend disbelief and go with the "Independence Day" tropes.

As one poster said, Astronomers are almost compelled to share findings.
