Large impact observed with Keck II telescope and its near-infrared camera at Mauna Kea on July 20 11:20 UT


"The Wesley impact occurred on Jupiter in July 2009 causing a black spot in the planet's atmosphere, similar in size to the planet's Little Red Spot and about the size of the Pacific Ocean. This impact scar is expected to last only a week or two as it becomes diluted by Jupiter's atmosphere."

I know. future like it may collide about the great red spot size.

[atomic7732]

Only if the object is big enough. The likelyhood of an object of that siz hitting Jupiter in this stage of our solar system is very, very low.

[monmarfori]

If an asteroid hits jupiter with 100 km. The Great Red Spot disappears.

[atomic7732]

Not if it hits the opposite side of Jupiter.

If an asteroid hits jupiter with 100 km. The Great Red Spot disappears.

Stop making claims that are unsubstantiated. Why do you think this? What evidence do you have for this claim?

[monmarfori]

I know. it occurs in some future centuries or millenniums.

[atomic7732]

And that's why no one else has heard of this how?

[monmarfori]

Jupiter is the largest planet. it would be hitten by an asteroid or comet about the size of oceans. like the 2009 impact of July.

[FGFG]

it wasn't the asteroid big as an ocean, but the crater it left in the Jupiter athmosphere (if we can call it "crater").
However was it predicted? It looks like it was a very big asteroid.

[Naru523]

It's a scar, not an impact.  monmarformi, the asteroid wasn't size as the ocean, the scar was, The Pacific Ocean at least.

[atomic7732]

It came in so fast and it flung gas out (obviously lighter than rock) so, it could have been (my guess) about 1-3 km across. Meteor crater was created by a 360 ft asteroid, and the crater is a mile wide. A collison into gas like that, is obviously goig to make a larger "crater" (scar).

[FGFG]

I don't think so...
It's quite difficult to find an example...

There is a cup full of smog (the best example i can find): if you throw a little stone into the cup (1 cm wide) i don't think that you will have a "scar" of meters wide (it was a very big cup ), even if you throw it very fast.

[atomic7732]

What if you threw it 30,000 km/s?

[FGFG]

I don't know . But gas is way less dense than water or rock.

[atomic7732]

Yeah, so it flys out more!

[FGFG]

Or it let solid things pass through it easier

[hbmp88]

OK, but what if it went in at a very steep angle.
