It's aspect ratio is very strange. It's length/bredth ratio is supposed to be around 10:1. Does the aspect ratio of any asteroid, whose shape we have calculated, come even close to that. Or even 5:1 or 4:1 ? regards Markus ID: 5664 · Rating: 0 · rate: / Reply Quote

Furthermore, it would be useful if the running program would automatically flag any asteroids with unusual shapes or extreme aspect ratios and posts a notice somewhere for someone to check it out. Who knows how many weirdly shaped asteroids we could already have calculated shapes for and the data is just sitting there waiting to be mined. ID: 5710 · Rating: 0 · rate: / Reply Quote

I told you it was an alien space probe. -- Joking. :>)) Stevo ID: 5750 · Rating: 0 · rate: / Reply Quote

Asteroid Cerberus is similarly elongated, its model is here: http://astro.troja.mff.cuni.cz/projects/asteroids3D/web.php?page=db_asteroid_detail&asteroid_id=310 ID: 5761 · Rating: 0 · rate: / Reply Quote

I'm glad to see Mr. Durech has joined our conversation here! The presence of such strange shaped bodies has been inspiration for many Science Fiction stories through the years. The shape of the 1865 Cerberus reminds me of a similar shaped object - 433 Eros In "The Expanse" - a SciFi TV series that I was watching recently, humans was built a base inside 433 Eros :) That was a lyrical deviation... Interesting fact is that those three bodies has similar average orbital speeds: Cerberus: Avg. orbital speed - 27.03 km/s Eros: Avg. orbital speed - 24.36 km/s Oumuamua: Avg. orbital speer - 26.33 km/s After passing the Sun on on Sept. 9, 2017, Oumuamua has developed speed of 87.3 km/s! Later when its speed was twice lowered it still has enough speed to escape Solar gravitational pool, passing the Earth's orbit at 49.67 km/s. Traveling with such speed it has been capable to cover the distance between Earh's and Mars's orbits in just 21 days - from Oct. 10 to Nov. 1, 2017. Amassing ha! Too bad that We was not ready for it. We could send a probe to it that could be its travel buddy during its fly, leaving Solar system. Imagine what amount of data could be gathered... What a beauty!
