Anyone else thinking of Rendezvous with Rama by Arthur C Clarke right now?

I'm thinking more like The Expanse.

I just finished the show (season 1 and 2) and it’s the best sci-fi I’ve seen. I find it more epic than BSG. I’m so happy I watched it. I am considering picking up the books now. The science is on point. Flip and burn baby!

I like to imagine some alien civilizations version of Voyager 1. Perhaps they sent us their own golden record with difficult to decipher pictographs and samples of pictures and music.

Some tabloid is already writing an article "First alien nudes from outer space discovered".

The object approached our solar system from almost directly "above" the ecliptic, the approximate plane in space where the planets and most asteroids orbit the Sun, so it did not have any close encounters with the eight major planets during its plunge toward the Sun. On Sept. 2, the small body crossed under the ecliptic plane just inside of Mercury's orbit and then made its closest approach to the Sun on Sept. 9. Pul…

I doubt that's possible, although it would be very interesting.

"The CNEOS team plotted the object's current trajectory and even looked into its future. A/2017 U1 came from the direction of the constellation Lyra, cruising through interstellar space at a brisk clip of 15.8 miles (25.5 kilometers) per second."

So we have an origin. However they don't give the error margin so is probably not possible to pin point the exact origin without further calculations.

I wish I had read the books before I watched the TV series. Doing it in the reverse order has made me fairly unmotivated to read, I'm a few chapters a in to the second book and not sure I'll continue.

Having said that, I've been fairly unmotivated to read anything recently due to working long hours and recently having rescued a dog.

Let Ne know how you go with it.

Technically, it would be the second. First in solar system was Voyager I: https://en.wikipedia.org/wiki/Voyager_program

It’s an interstellar object, but not in the solar system (it used to be, but wasn’t interstellar until it left)...

A probe sent out by some remote civilisation, it is on its way through our part of the Milky Way galaxy. It used Sol as a source of gravity to slingshot itself on its way in the direction of Pegasus. It also did some measurements while it was at it, even though this system is not its final destination. Yes, totally made up but in theory it would be possible.

Just make sure you aim to miss all of the planets around it ;)

And that you are far away from Sol to not burn on it

It's an interesting concept to think about

I'm so glad that The Expanse has brought great space opera to the masses. Scifi books are several orders of magnitude better than the majority of "Scifi" Hollywood movies.

The struggle of a fledgling technological species against the plight of interstellar space is a majestic backdrop for many of the best novels I've ever read. Especially with Clark, Niven, Pournelle etc. that have done some excellent mathematical investigation into the feasibility of the concepts discussed.

It's an amazing series. Highly recommend it.

The series is awful. Original Rama is awesome but then some co-author takes over and it becomes a mess. The dude definitely had problems.
