A New 'Interstellar Visitor' Has Entered the Solar System (livescience.com) 58
Astronomers have detected a mysterious "interstellar object," dubbed A11pl3Z, speeding through the solar system at 152,000 mph. If confirmed, it would be just the third known interstellar visitor, following 'Oumuamua and Comet Borisov. The visiting space object will pass near Mars and the Sun later this year before leaving the solar system forever. Live Science reports: The newly discovered object, currently dubbed A11pl3Z, was first spotted in data collected between June 25 and June 29 by the Asteroid Terrestrial-impact Last Alert System (ATLAS), which automatically scans the night sky using telescopes in Hawaii and South Africa. The mystery object was confirmed by both NASA's Center for Near Earth Object Studies and the International Astronomical Union's Minor Planet Center on Tuesday (July 1), according to EarthSky.org.
A11pl3Z is most likely a large asteroid, or maybe a comet, potentially spanning up to 12 miles (20 kilometers). It is traveling toward the inner solar system at around 152,000 mph (245,000 km/h) and is approaching us from the part of the night sky where the bar of the Milky Way is located. Based on A11pl3Z's speed and trajectory, experts think it originated from beyond the sun's gravitational influence and has enough momentum to shoot straight through our cosmic neighborhood without slowing down. However, more observations are needed to tell for sure.

FWIW his grad student at the time had the better ideas, involving relative motion of solar systems within the Galactic Plane. His models were the best fit for the available data.

Yeah the Rama movie has been in production hell for decades now but recently Denis Villeneuve got attached to direct after he's done with Dune 3 and/or James Bond or the other 3 projects he's got lined up so I still give it a 50/50 shot it gets made still.
I imagine whoever owns the rights doesn't want to sell them or I'd imagine it would be a prestige-TV series by now but I'd be happy to see his version of the story.

If it does get made into a movie finally I don't have very high hopes. The entire story revolves around nothing but the thrill of exploration and mystery behind Rama which is left unknown in the book. Fantastic story, fantastic read. A product of the time. Not sure it would make a popular movie though. No doubt they'd have to add pointless interpersonal conflict like they did in the later Rama books, which weren't nearly as good. Also as the explanation behind Rama was revealed in the books, it was kind

The sun is hurtling around the solar system at ~230 kps (relative to the local standard rest frame), but so is the asteroid.
Since both objects can be considered to be orbiting the milky way at the same speed, we generally consider that speed to be zero for the purposes of comparison, and only compare the two objects motion relative to each other.

Re: (Score:2)
I think it's assumed that the speed is relative to the solar system.
The solar system consists of multiple objects each with velocities that differ enough to make the question about which part of the solar system the object's speed is measured relative to important. Logically it would make the most sense to quote the speed relative to the Sun but since I'm guessing the speed measurement was done from Earth it may be relative to us. The difference in velocity between the Earth and Sun is sufficient that it makes a big difference.

I know that a decade or so ago we did not have the ability to detect and monitor all objects capable of destroying life on Earth yet. Do we now have that ability? Are we now identifying and tracking every potential candidate of that kind, or is that even possible?

No, we aren't tracking EVERY object of that kind. (You didn't say all, so that includes the meteor that hits a gopher in his hole.)
Possible? Yeah, I think it's possible. It would be a bit expensive. We're tracking most large objects that cross Earth's orbit. New ones don't appear very often, and we rarely lose track of any. It would take multiple observatories in places outside the plane of the solar system to track all of them, so we've been surprised occasionally by "city killer" meteors, though non
