the other is from the dust i think and a bit off from the other tail positionally.
as they approach the sun the ice is burned off and creates the tail. jupiter protects earth a bit due to its gravity intercepting asteroids.Ĭomets: balls of ice, dirts/dust, and gases held lossely together by gravity. The rest of those papers seem like pretty straightforward physics and math problems with all the informatiion given.Īsteroid: a rock in space, there's a belt of them, they often orbit jupiter and the sun. those videos mention all those things as they have happened and also usually use the scientific names. since i see they have things like meteor showers, retrograde of a planet, moon passing in from of a planet, etc. it will familiarize you with common events that might be used in these papers. they're 3 months long and usually just say what astronomical phenomenon are happenening that month, including the brightnesses of those events regarding the scale that is used for the brightness of astronomical objects. Otherwise nasa does this monthly in the sky video. also see if they have a prep/sample/stufy book or guide.
Seriously though, those old papers/models/solutions may be your best source.
