The Yarkovsky Effect
-
“The asteroids get their energy from the Sun, a lot of that energy, especially on a dark asteroid like Bennu, is absorbed, causing the asteroid’s surface to heat up. It has to release that energy back out into space, and when that happens it acts likes like a thruster and changes the trajectory of the asteroid. “So if you want to be able to predict where an object like Bennu is going to be in the future, you have you to account for this phenomenon, and we’re going to provide the best-ever scientific investigation of this fascinating concept.” OSIRIS-REx probe launched to asteroid in compelling search for the origins of life – Spaceflight Now[^] Marc

That's really interesting. Very cool to think about how energy is absorbed and then used in a different way and how it actually creates a form of propulsion in space. Wow.:cool:

What if our slight interaction with the asteroid changed its trajectory just enough so that Earth might experience a very bad day a few years from now? :~

I wish I had an "EFFECT" named after me. So far, I've only got Murphy's Law, and they misspelled my name completely.

You are joking, yet unsure. They (who's they anyway?) say that jokes contain a minimum of 20% truth - the more truth, the greater the impact of the joke. I agree with your joke. :)

So if you heat something that's made of a combination of materials up, some of the materials may expand and be ejected, causing a change in the angular momentum of the object? Like, does that really need a special name? I smell the need to publish a paper or lose tenure. Me, I'd call it The Bleeding Obvious Effect.

It's not that material is ejected, it's that the heat radiates back out into space and acts as "thrust." Marc

Seriously? So it's just radiated photons? That means that we're talking of an effect that is so infinitesimal that we may never even be able to conclusively prove that it exists*, because it will be hugely overpowered by proven/provable effects. Hell, you could equally say that the Earth's rotation and orbit are affected by the way it absorbs/reflects light, but the mass involved not only makes it impossible to prove, but also makes it unlikely to be true -- you exert a lot more force by slightly opening a tap (faucet) and letting water dribble into the sink. * Except in abstract, of course, but I suppose that that's why numbers and "career mathematicians" exist.

Not necessarily. The effect was first measured in 1991–2003 on the asteroid 6489 Golevka. The asteroid drifted 15 km from its predicted position over twelve years (the orbit was established with great precision by a series of radar observations in 1991, 1995 and 1999) from the Arecibo radio telescope.[3] source[^] Marc

Good Lord! No sooner do I mention affirmation of the consequent in one posting, but I find an example of it in another posting! How synchrowhatzitous! The thingy drifted 15 km, therefore it was caused by the Yarkovsky effect! ... Or maybe it hit a 3cc pebble, somewhere in the millions of miles that it travelled.
