Meteor storms appear tomorrow

Space agencies around the world are concerned that tomorrow's meteor shower could turn into a storm and threaten artificial satellites on Earth orbit.

National Geographic quoted astronomers as saying Draconid meteor shower will appear tomorrow. The number of supernovae falling tomorrow could reach 600 streaks per hour - much larger than the Perseid meteor shower rate in August - so one could call it a meteor shower . The falling rate of a meteor is about 20km / sec.

The time when Draconid meteor shower peaks will take place during the day in the western hemisphere so people will have difficulty observing by sunlight. In contrast, meteor shower falls most strongly at night in the eastern hemisphere. However, the phenomenon of the full moon makes it difficult to observe the meteor in the eastern hemisphere.

With the number of meteors falling can reach 600 streaks per hour, the rain
Draconid meteor tomorrow can turn into a storm.

'All people in North America will not be able to watch Draconid meteor in the peak period. Observers in Europe and Asia may have a better chance , 'commented Raminder Singh Samra, an astronomer at HR MacMillan Space Center in Canada.

The possibility of the "Draconid meteor storm" makes the US Aerospace Agency (NASA) and the space agency in many other countries worry that it may adversely affect the International Space Station (ISS) and other Artificial satellites are revolving around the earth.

'In every meteor shower, artificial satellites and ISS always face the risk of colliding with cosmic dust particles. We have no way to avoid that risk, except hopefully the collision will only cause a small impact , 'Samra said.

Meteor shower has caused damage to many artificial satellites in the world. The European Space Agency's Olympus satellite lost its balance and rotated after the Perseid meteor shower in 1993. Perseid meteor shower also caused Landsat 5 satellite to lose balance and leave orbit in 2009.

However, some experts believe that the risk of damaging the artificial satellite of the Draconid meteor shower will be low, because the meteor will move at nearly half the speed of other meteor showers. . In fact, Draconid is one of the slowest meteor shower. So they thought that Draconid meteor could not turn into plasma after colliding with the artificial satellite tomorrow.

Last year NASA considered the possibility of changing the International Space Station and Hubble Space Telescope's trajectory so they could be safely in place when meteor showers took place.

Every year the number of supernovae in the Draconids meteor shower is relatively low. But after about 13 years the number increased very strong because the earth moved through the area with the most dense dust particle density in the Draconids meteor shower. In 1933, people on Earth could see 54,000 meteors every hour in ideal conditions. But by 1946, that number had dropped to 10,000 meteors every hour.
