Asteroids are large space objects made of rock and ice. There are hundreds of thousands of asteroids in our solar system. Though we often hear ideas about establishing colonies of humans to live and work on our Moon or our neighboring planet, Mars, some think that sending people to an asteroid would actually be the best colonization option for a number of reasons Low Gravity To begin with, asteroids are often much smaller than planets, so they have lower gravity. When landing a spaceship, the craft would not be pulled as strongly or as forcefully toward the asteroid's surface, making the landing safer than landing on the Moon or Mars; it would also allow a spacecraft to carry much more equipment needed to set up the colony. It would also be easier for the spacecraft to take off again, so the spaceship would need to carry considerably less fuel for the trip back to Earth. Mining Valuable Metals Next some asteroids are rich in valuable elements and precious metals that are relatively rare on Earth, such as gold and platinum. An asteroid colony would be extremely profitable and a good source of these raw materials. The colonists or businesses sponsoring them could more than pay for the cost of their support by mining minerals and sending them back to Earth. Easy to Reach Finally, asteroids are a good option for colonization because some of them would be very easy to reach. There are a number of asteroids that periodically come within or near Earth's orbit Some of them actually get closer to Earth than our Moon. So these asteroids would be much easier and more affordable to get to and get back from than a planet like Mars, which would require a two-year trip in each direction.

The lecturer explained why asteroid will not be a great place for colonization. These are the following three reasons.
First of all, asteroid has lesser gravity. As a result of lesser gravity there are more chances of getting health problems including less bone density and lesser muscle mass. Due to this condition people cannot stay or colonize in asteroid for long. This directly refutes the reading passage which support the idea of lesser gravity suiting better colonization in asteroid.
Secondly, lecturer also thinks that mining valuable from asteroid is also not practical due to the cost of transportation and support. He also says that due to the huge supply of valuable metals from asteroid, can lead to less market demand. Again this contrasts the reading passage which states that asteroid colony would be profitable from metal mining
Thirdly, most of the asteroid does not stay close. Moreover they move far away from earth, so this can be challenging to way back to earth.Thus lecturer clearly explains that the idea of reaching asteroid easily cannot be also not considered as a good reason for colonization in asteroid.
All in all, due to serious health hazard, cost involved in mining precious metals and difficulty to reach back to earth from asteroid are the main reasons why professor think that colonization in asteroid is not a good idea.
