The shooting star might be the thing that you admire as a kid, but the sky phenomenon has also become a strong warning that the Earth is not alone in the space, and the number of the space objects could become a hazard.

"We must make it clear that it will not happen," said Donald Yeomans, a senior researcher at NASA's Jet Propulsion Laboratory in Pasadena, California, and author of "Near-Earth Objects: Finding Them Before They Find Us" (Princeton University Press, 2012), as told to Live Science.
When the comet was last seen in 1992, Yeomans was making revisions models of comet movement, making complicated calculations to measure the gravitational effects of the sun and planets on the object space rocks.
Of sightings in 1992, plus the data from 1862 and 1737, showed that astronomers have enough information to find the possibility of a collision in 2126. Keep in mind, Comet Swift-Tuttle instead of the usual space rock.

But the size of the comets or asteroids not be the only thing responsible for cosmic collisions, said Gerta Keller, a geographers at the Princeton University.
The fall of the comet to land or sea may cause destruction in the surrounding area, but the real devastation comes from the gas in the stratosphere, part of the Earth's atmosphere where the ozone layer is located. Sulfur dioxide causes cooling, heat and carbon dioxide causes long term heating, added Keller. This led to drastic climate change and brings mass extinction worldwide.
Keller also explained that most of the Earth is ocean. Effects caused able to impact on the deep sea, such as the eruption of underwater volcanoes.
Based on the Scientists calculation, the arrival of the comet Swift-Tuttle to the Earth on August 5, 2126, within a distance of 14 million miles, equivalent to 60 times the distance of Earth to the Moon. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]Note: This blog can be accessed via your smart phone
