Going to be hit by an Asteroid?

The Taurid meteoroid stream produces a low number of meteors and a meteor shower usually in October and November. The branch includes asteroids having diameters more than 200 meters, and it is unclear if any of them has a trajectory collision with Earth, although no such situation has been found yet.

However, to be cautious many Space organizations have Collision monitoring system that routinely scans for asteroids and determines the probability of a collision. One such system is Sentry, used by NASA.

Asteroids and comets are usually influenced by Jupiter’s strong gravity, which makes them re-direct towards the Earth or nearby planets. One such meteor shower took place in 2015 caused by comet Encke’s redirection, when astronomers analyzed 144 Taurid meteors that produced a large flash when they hit the atmosphere.

So basically, our civilization is still safe as of now. No external forces causing any troubles. What about the internal forces though?

An asteroid to pass ‘close’ to Earth

#space #asteroid #Earth #2014JO25 #SolarSystem

An asteroid, named 2014-JO25, will pass through Earth at a distance of 1.8 million kilometers, (five times the distance from the moon). The asteroid stretches 650 meters across and is believed to pass Earth today.

The asteroid will pass closest to Earth after having looped around the Sun, and will continue on past Jupiter before heading back toward the center of our Solar System.

The last time an asteroid of this size or bigger passed was in 2004, named Toutatis, which was five kilometers across, and passed within four lunar distances.

2014-JO25 is beileved to have passe Earth previously around 400 years ago, and will pass Earth again in 2600.

You can watch the asteroid through a telescope, because the next time if someone lays eyes on it, they will probably be your grand-grand-grand-grand children.
