what are the difficulties of studying asteroids??

Question

what is difficult for nasa or astronauts to study asteroids???
this is for a project.pls help

Answer 1

The asteroid fragments that we see today lay mainly between the fourth and fifth planetary orbit rings around the sun, that is, between the orbits of Mars and Jupiter.
It is highly probable that those fragments are what is left after a major collision between a large asteroid and something obiting the Sun in that space between Mars
and Jupiter.

The difficulty in making any serious study of these fragments has to do with their smaller size (compared to planets and Moons) and their relative high speed of travel around in their orbits. Irregular asteroid surfaces suggest that they were chunks of already cooled and solidified material when born (broken apart from the main object).
The irregular shapes tend to make radio signal bounced off of them fluctuate. Thus it is difficult to make use of possible information from the radio signal reflections.

More than 15,000 astreroids have been charted to determine their orbital paths.

Asteroids also lead and follow Jupiter around as it orbits the Sun. Those asteroids lay about 1/6 of an orbit in front of Jupiter, and 1/6 of an orbit behind it. These asteroids are called Trojans as a general grouping.

There are some 200 asteroids which have orbits crossing the Earth's orbit and may some day crash into it. Probably ten times that number exist but have not been discovered yet.

Answer 2

They are small and so have very low gravity. It would be hard to land and walk around without bouncing really high On some of the smaller ones a person could actually jump into orbit! Also, they are much farther away than the Moon and no manned mission has even gone farther than the Moon. But some unmanned missions have gone to asteroids. The source is the web site for one of those missions.

Answer 3

Two of the difficulties I can think of are the varying sizes of the asteroids, from microscopic particles to boulders the size of mountains, and their orbits. The orbits vary from being almost circular in the asteroid belt between Mars and Jupiter, to being very eccentric and tilted with respect to the orbits of most planets.

Answer 4

Their orbits are basically one of the hardest obsticles to get around because of their constant bumping and collisions with other asteroids. The fact that they are also small compared to other heavenly bodies also adds to the difficulty.

Answer 5

becuase some astroids move at a fast pace and somtimes it make it easier if you watch it day and night. but most of the time ti takes nasa to find a long time.

Answer 6

Getting hit

Answer 7

they're far away, they move very fast, their surfaces are very jagged and uneven making it nearly impossible to safely land on them (although it has been done once). etc. etc.
