I guess it would be possible that it crashed into the sun, if it had the right trajectory, but it wouldn't have had any effect; the thing is 50 - 130 meters, while the sun is nearly 900.000 KILOmeters in diameter. It would likely have burned up before even reaching the surface of the sun. Even if it was idk, a huge nuclear weapon that detonated before melting, it wouldn't matter because the sun already is a huge fusion nuke. It does coronal mass ejections regularly that, according to a pop sci article I just read, already has more energy than 20 million nuclear weapons - anything that would end the sun would have to be several orders of magnitude stronger.
> Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space.
An image which accurately shows both the Sun and other objects to size or at the correct distance doesn't give you an accurate measure of scale. Movies which show space sequences and ships flying from one planet to the other don't help, either.
An image of the Solar System which shows both the Earth and Sun in the same image is either distorting the size of the Earth, distorting the distance between the two, or both. Here's one tool that may help...get your scroll wheel warmed up, though:
Or maybe you could visit one of the many to-scale solar system models, and take a walk from a 1-meter-diameter sun 100 meters away to a 1-cm-diameter Earth and continue walking for 30 minutes to the outer planets.
At 1 meter scale for the Sun, Oumuamua is 0.1 microns, or 1/10th the size of a bacteria. If we multiply everything by 10,000 until the object is a 1mm grain of rice, now the Sun is 10 km in diameter, the size of a small city. Nothing the grain of rice could do, no matter how fast it moves or what it's made of, would harm the city-sized ball of fire. Granted, a 130 meter high-density (not Oumuamua) high-velocity asteroid impacting the Earth (100 meter diameter in our scaled-up rice-grain model) would cause significant distress for the very environmentally sensitive organisms clinging in a thin film to its surface (namely, humans), especially near the impact site.
Would have it been possible for thie Oumuamua to directly crash into the sun and just... end our solar system? Just like that?
