I guess they're saving the name 'Rama' for the first one we rendezvous with?

Soooooooo how's its light curve?
Who even made the rule that we cannot group ducks and fish together for the simple reason that they are both aquatic? If I want to group them that way and it serves my purpose then I can jolly well do it however I want to and it is still a nested hierarchy and you can't tell me that it's not.

Nice.  Can't help but speculate that it's perhaps an irregular-shaped chunk of ejecta from some collision in its parent solar system which punted it free of the local gravitational well. Must be a large number of such wanderers out there.

they should shoot something at it to see if it's made of antimatter.

Even odds it's an alien spaceship.

Normally I'd find that speculation agreeable but just recently I learned that all of that material hanging around out there is actually pieces of the Earth. These pieces were ejected after the tides pumped up the continents, like overfilling a shitty waterbed, until finally the planet's crustal sphincter blew it's collective pant-load and thrust all sorts of stuff into outer space during the global flood. All that stuff became the comets and asteroids. Turns out the Earth was like some gigantic extra-solar whoopee cushion.

Might even be some flash-frozen dinosaurs and whatever spinning wildly out of control out there, ready to thaw and BBQ. Can you imagine what you could charge for T-Rex T-Bones or some Stegosaurus Sirloins ?  Elon needs to get on this shit stat.

Light curve of interstellar asteroid `Oumuamua




I wonder how many news websites discovered a bug in their publishing systems' handling of the backtick character, thanks to this object's name?

It's all fun and astronomical science....until the missile bays open up and lock on.

Here's the origin of the name.

Project Lyra, a mission to chase down that interstellar asteroid

But of course, rendezvousing with this asteroid presents many challenges. The most obvious is that of speed, and the fact that 1I/`Oumuamua is already on its way out of our Solar System. Based on calculations of the asteroid's orbit, it has been determined that 1I/`Oumuamua is traveling at a speed of 26 km/s - which works out to 95,000 km/hour (59,000 mph).

This is considerably faster than any object humanity has ever launched into space. Voyager 1, the fastest object humanity has ever built, has a hyperbolic excess velocity of 16.6 km/s. As 1I/'Oumuamua is already leaving our solar system, any spacecraft launched in the future would need to chase it.

To summarize, the difficulty of reaching 1I/'Oumuamua is a function of when to launch, the hyperbolic excess velocity, and the mission duration. Future mission designers would need to find appropriate trade-offs between these parameters. For a realistic launch date in 5 to 10 years, the hyperbolic excess velocity is of the order of 33 to up to 76 km/s with an encounter at a distance far beyond Pluto (50-200AU).

Alien object 'Oumuama was a natural body visiting from another solar system

Professor Alan Fitzsimmons headed up a team which measured the way that `Oumuamua, reflects sunlight, and found it similar to icy objects covered with a dry crust. This is because `Oumuamua has been exposed to cosmic rays for millions, or even billions, of years, creating an insulating organic-rich layer on its surface.

The research, which has been published this week in Nature Astronomy, suggests that `Oumuamua's dry crust could have protected its icy interior from being vaporised - even though the object was just 23 million miles from our sun in September when it zipped past.

Professor Alan Fitzsimmons commented: "We have discovered that the surface of `Oumuamua is similar to small solar system bodies that are covered in carbon-rich ices, whose structure is modified by exposure to cosmic rays.

"We have also found that a half-metre thick coating of organic-rich material could have protected a water-ice-rich comet-like interior from vaporizing when the object was heated by the sun, even though it was heated to over 300 degrees centigrade."
