Wouldn’t such an object be emitting radio signals that earth could receive?



Not if it's something like another civilization's Tesla Roadster.

'Oumuamua is red and headed toward Pegasus (the winged horse) after a very long journey starting longtime in spacetime ago. It is wildly tumbling off-kilter and potentially creating a magnetic field that would be useful for interplanetary spacetravel.

They're probably pointing us to somewhere else from somewhere else.

If this is any indication of the state of another civilization's advanced physics, and it missed us by a wide margin, they're probably laughing at our energy and water markets; and indicating that we should be focused on asteroid impact avoidance (and then we will really laugh about rockets and red electromagnetic kinetic energy machines and asteroid mining). https://en.wikipedia.org/wiki/Asteroid_impact_avoidance

Maybe it would've been better to have put alone starman in the passenger seat or two starpeoples total?

Given the skull shape of October 2015 TB145 [1] (due to return in November 2018), maybe 'Oumuamua [2] is a pathology of Mars and an acknowledgement of our spacefaring intentions? Red, subsurface water, disrupted magnetic field.

In regards to a red, unshielded, earth vehicle floating in solar orbit with a suited anthropomorphic creature whose head is too big for the windshield:

Right. As unlikely it is to run on other civilizations remainders, there is quite some chance for future humans to have a surprise find of a 2008 Tesla roadster :)


Only if it is actively emitting them. So if the aliens sent an active probe, it might emit radio signals. But if it is some junk from an alien civilization, it would just be trash drifting by. It would still be increadibly interesting to catch such an artifact.


Just another roadside picnic?
