So now they can name the second one they find, "first loser."
Basically, the camera is moving from roughly behind the object to roughly in front of it, so the object is travelling backwards relative to the camera (but continues to advance along its heliocentric trajectory).Perhaps someone could explain a confusion I have about the video by Tex in post #53. At about the 1:30 point in the video it looks like the asteroid is going backwards. Can someone explain that?

I just made the following scenario, using the state vectors from JPL HORIZONS. I was surprised to find the Y and Z axes seem to be flipped between Orbiter and JPL, but substituting one for the other resulted in orbital elements in the scenario editor that matched JPL's elements. Propagating forward seems to result in reasonable accuracy in the earth encounter distance. I made Oumuamua a default DG, feel free to replace with your object of choice.Or an Orbiter scenario. I'll work on it at some point.

That is the conclusion of new Belfast research that has examined in detail the light bouncing off the cigar-shaped asteroid from outside our Solar System.
"At some point or another it's been in a collision," says Dr Wes Fraser from Queen's University.
His team's latest study is featured in Sunday's Sky At Night episode on the BBC and published in Nature Astronomy.
And probably the first people in line to pay that fortune would be scientists wishing to analyze it! :lol:We should send a robot, drill that asteroid and bottle the water. People would pay a fortune for a Litre.
Alien Bottled Water, big sales(till the side-effects start showing).

An object from another star system that made a brief appearance in our skies guised as an asteroid turns out to be a tiny interstellar comet.
‘Oumuamua, a name that reflects the Hawaiian meaning for ‘a messenger from afar, arriving first’, was discovered by astronomers working with the Pan-STARRS survey in Hawaii in October last year as the object came close to Earth’s orbit. Follow-up observations by ESA’s Optical Ground Station telescope in Tenerife, Canary Islands, and other telescopes around the world helped determine its trajectory.
