Asteroid

Where is it, and how does it compare in size to our planet and sun?
How big is it?

a balck hole

that has the size of a galaxy like our own

few billion times larger

Or is it that satellites get hit a lot, and no one says anything about that?

The earth DOES go through an arm of the asteroid belt that extends very close to earth’s orbital path that’s why we get spectacular metior showers every november.

now that that is out of the way.

yes sometimes satelites and or the spacestation do get hit. in fact they are more often getting hit than not. they are under nearly constant bombardment however like was earlier said most of what hits them is smaller than grains of sand. if they were to get hit by something largish though depending on where it hit exactly and how it is very likely that it would cause MAJOR damage. ultimately resulting in the satelites decaying orbit and eventuall reentry. this sort of thing happens all the time. personally i’m waiting for hubble to take a right good one right in that pretty little mirror it’s got. that will be one great big and expensive I TOLD YOU SO!

as for the space stasion. some of its components are like 15 years old. most of us don’t even have cars that old. we are talking potential for irreparable damage and Cascade FAILURE. any # of things could happen including but not limited to Explosive Decompression.

It is in low orbit.

First grade is so tough. Not only do they makes us learn math, but astronomy too!

That’s Asteroid, not Astroid. lol
Did I forget to mention that it is solid iron in the normal (earth surface) temperature and pressure range?

My guess, First Grade

Kepler’s Third Law:
Assuming density of iron: STP
? = 7874 kg/m^3
T^2/R^3 = 4 ?^2 / (G Mi)
T^2/R^3 = 4 ?^2 / (G [? 4 ? R^3/ 3] )
T^2 = 3 4 ?^2 / (G ? 4 ? )
T^2 = 3 ? / (G ?)
T = ? 3 ? / (G ?)
T = 4235.23 s
T = 1.176 hr

i really wanna know what movie it is.

at the end,a teenage boy and a teenage girl are holding a baby at the top of a hill.

before that a huge astraoid falls into the ocean and floods tons of it. and there was another astroid coming but the astronauts put their lives on the line to save the world.

please helpp.

Deep Impact.
The same time Armageddon came out with Bruce Willis and Ben Affleck.

Same concept, but Deep Impact was better.

It may be a comet and I’m not positive on the year it may be 2036.

it won’t hit.

Nasa on 99942 Apophis

http://neo.jpl.nasa.gov/apophis/

truncated quotes from that nasa article:

"The future for Apophis on April 13, 2029 includes an approach to Earth no closer than 18,300 miles."

"New measurements in 2013 will likely confirm that in 2036 Apophis will quietly pass more than 30.5 million miles from Earth"

rumor is they plan to send a few probes to Apophis in 2029, during its first approach and attempt to steer it off course just to see if they can.

(hmmmmm hey wait a minute that’s a Friday the 13th in 2029. Hope your not superstitious)

I really need to know this for an exam on things like this!!!
And I need to know how s tha I can write this down! With supporting answers!!!
Thanks in advance!!!

Well if by a different of rock you mean into like a different, like from one kind of rock to another, well their mostly made from metals like iron and tin so it’s unlikely they’d become another metal in a place with no pressure or heat.

However one might become a meteorite at it passes through the earths atmosphere, if it becomes less than 10 metres wide. If thats what you meant.

Questions kinda vague
