Objects in Space

Many objects move around in space that proves to be a threat to the planet earth and its components. There is a chance of collision in relation to the number of objects in the space thus the need to adopt and implement preventive or tracking measures towards minimization of the effects. One of the effects of the collision of the numerous objects moving in the space is death of the humanities in extreme circumstances. Luckily, for the development of human beings, space is empty. It is also essential to note there is critical information or knowledge on the locations of the large objects in the space. This makes the chances of DS1 hitting any object accidentally to be very slim. Despite this essence, there are small objects in the space that eludes the knowledge the humanity in relation to the exact location. This makes DS1 to be a possible outcome of the collision. The DS1 systems are very fragile thus are applicable in the vacuum of deep space hence elimination of contact with any object. It is also essential to note that DS1 systems are experimental thus no idea on how they would fall.

What objects?

Various objects would prove to be dangerous to the development and growth of humanity. In the execution of this research exercise, the focus will be on the meteors/meteorites and asteroids with reference to the examination of the potential influences or implications to the human beings.


A meteor refers to the bright streak of light in the sky (in the form of a shooting or falling star). The cause of the meteors is the entry of the small meteoroids within the context of the earth's atmosphere. These objects are visible in dark clear skies. Very bright meteors are known as fireballs thus the need report such cases whenever they occur. Meteorites refer to the bits of the solar system hitting the planet earth. Most of them emanate from asteroids, comets, and Vesta. According to the scientific examination, it is essential to note that few cases indicate lunar systems and Martian with reference to meteorites. Only large meteorites have the capacity of reaching the earth. The largest case of meteorite to have been found on the planet was Hoba in Namibia (approximately 60 tons). It is essential to note that asteroids have no atmosphere despite the fact that most of them are large enough to initiate and sustain gravitational pull. Asteroids have massive information in relation to the formation of the solar system approximately 4.6 billion years ago. It is essential to note that a meteor is a form of asteroid that burns or vaporizes following the entry into the earth's atmosphere.


An asteroid refers to a rocky object within the space, slightly smaller than the planets (O'Brien et al. p. 44). In other cases, they are called small planets or planetoids in accordance with NASA. They are space debris resulting from the leftovers of the fragmentation during the formation of the solar system. There are millions of asteroids moving around the sun. Approximately 750,000 of asteroids found within the asteroid belt between the orbits of Jupiter and Mars. There is a possibility of asteroids being larger than hundreds of kilometres wide (O'Brien et al. p. 45). For instance, there is the essence of asteroid Ceres. Sometimes, this asteroid is known as a dwarf planet. It is approximately 940 km or 584 miles in width.

Why should we be concerned?

Effect in the past

In the recent years, there have reports on two different asteroids which were considered possible threats to the planet Earth. Fortunately, critical examination of the two objects revealed a reduction on the effect to the potential strike or threat of the two objects. Despite this essence, it is still ideal to determine the number of occasions the earth has avoided the effect or bullet in relation to the objects in the space. There are dozens of objects which prove to be very close to the proximity of the earth at any time. In 2000, two objects were found. According to the celestial objects, these objects were number two and three respectively in the list with reference to close approaches (Simonov et al. p. 579). In 1994, the planet kept track of the closest approach in which 1994 XM1 came within approximately 112,000 km.

It is essential to note that the earth has experienced strikes in the past. In 1908, there was a strike in relation to the formation of Tunguska River in Siberia thus devastation of a huge area of land in the process of the strike. There have been such strikes in the history of the planet earth. Approximately 65 million years ago, there was a collision between the earth and a large comet/asteroid (Barras p. 11). The outcome of this collision was the elimination of approximately of 75% of the planet's life forms inclusion of the large reptiles in the form of dinosaurs. Another recent implication of the objects in space is the effect of the iron meteorite in relation to the modern day Arizona (Simonov et al. p. 581).

The eventual outcome of the event was a formation of a crater approximately 34 miles wide. Such collisions have the ability and capacity to destroy life within the range of hundred miles with reference to the impact site or zone. The presence of these effects in the past should propel the earth in the determination if humanities are overdue for such implications under the influence of the objects in space. This relates to the development of various plans following identification of such events. It is, therefore, vital for the protection of the world against any accidental strikes in relation to the objects in the space (Simonov et al. p. 583).

Effect in the future

The fireball in the case of Russia in 2012 was an indication of the need for the earth to adopt and implement various precautions for protection against objects within the space that pass the planet on a frequent basis. It is essential to note that space objects will be bigger/larger thus the development of the capacity to cause considerable damage in case of a strike of the planet earth. The eventual outcome of such strikes, like in the past, would include transformation of the life forms of the planet. There will be a devastation of the majority of the components of the planet. It is also essential to note that Jupiter implication raises the essence of future asteroid strikes thus the need for the earth to adopt and implement effective and efficient approaches towards minimization of the influence or impacts of the strike. The strike of Jupiter by a comet/asteroid raises the chances of the earth being hit by an object in the space. The bruises of Jupiter have faded away but it is vital to focus on the protection of the planet for the safety of humanity, plants, and animals to minimize the essence of implications like in the previous encounters.

What can we do?

The main objective of the scientists should be protection of the planet against accidental strikes by the objects in the space. This is through integration of technology and other resources in enhancing security and safety of the planet earth and its components. There are two critical approaches towards minimization of the threats and impacts of the accidental strikes of the earth by objects in the space: tracking & prevention.


NASA focuses on the implementation of technology in the tracking of the objects in the space with the aim of minimizing the damage or implications like in the past encounters. This is vital for the enhancement of the security of the humanities, plants, and animals within the planet earth. NASA places critical emphasis on tracking of the asteroids and protecting the planet earth against the strike of the objects in the space. This is through implementation of flyby to offer unique opportunity for the researchers to examine or study any near-earth object closely (Asteroid Detectives p. 5).


Identification of the near-earth objects is the first approach towards prevention of the strike or collision. The next step following identification is collection of valuable information on the object through application of ground based and space telescopes. Following the collection of information on the size, mass, and composition, there is an analysis of the data on the earth with the aim of developing an appropriate prevention approach. There are difficulties in the prevention of the strike of the planet earth by large objects in the space (Asteroid Fly-By p. 4). One of the essential methods is the implementation of nuclear bomb thus diverting the objects from the course. This is through detonating a nuclear weapon thus knocking the object off its course. Another method entails attaching of a rocket motor on the object in the space with the aim of diverting its course. Early detection plays critical role in the effectiveness and efficiency of this method of…
