NASA reveals that from tonight TWO asteroids will be straight through & # 39; Earth & # 39; s neighborhood & # 39; fly
- Asteroids are estimated at around 400 to 850 feet and 950 to 2,100 in size
- First, called 2010 C01, his closest approach comes at 11:42 PM. EDT on September 13
- The second is on the heels and passes the earth at 7:54 pm. EDT September 14
- They are about 14 lunar distances from the Earth, or about 3.5 million miles away
According to NASA, the cosmic neighborhood of the earth will be visited by two medium-sized asteroids this weekend.
The space agency has followed the two objects 2010 C01 and 2000 QW7 in the past two decades and estimates them to be several hundred meters in size.
Fortunately neither of these are threats to our planet.
Asteroid 2010 C01 passes just before midnight on Friday, followed by 2000 QW7 on Saturday evening.

The space rocks are estimated at around 400 to 850 feet (120 to 260 meters) and 950 to 2,100 (290 to 650 meters), respectively.
The first one comes closest at 11:42 pm. EDT on September 13 with the second on the right heels, beyond Earth 7:54 pm EDT September 14.
During the flyby they are about 14 lunar distances from the Earth, or about 3.5 million miles away.
Both asteroids are what scientists regard as objects near the earth. Objects in this class revolve around the sun and sit near the Earth, or within 30 million miles of the orbit of our planet, NASA says.
The space agency keeps track of this through the work of its Near-Earth Object Observations Program, which monitors their activity and calculates future near approaches and impact potential.
Although scientists are still sometimes overwhelmed by objects that can evade detection, there are no surprises with the two that will meet us this weekend.
"These asteroids have been well observed – one since 2000 and the other since 2010 – and their jobs are well known," says Lindley Johnson, planetary defense officer and program director for the Planetary Defense Coordination Office at NASA headquarters in Washington, DC.
"Both asteroids pass about 14 lunar distances from the Earth, or about 3.5 million miles away, but small asteroids pass the Earth so close."
WHAT ARE THE DIFFERENT TYPES OF SPACE ROCKS?
A asteroid is a large piece of rock that remains from collisions or the early solar system. Most are located between Mars and Jupiter in the main belt.
A comet is a rock covered with ice, methane and other compounds. Their orbits take them much further out of the solar system.
A meteor call astronomers a flash of light in the atmosphere when debris burns out.
This debris itself is known as one meteoroid. Most are so small that they are evaporated into the atmosphere.
When one of these meteoroids reaches the earth, it is called one meteorite.
Meteors, meteoroids and meteorites are normally from asteroids and comets.
For example, when the earth passes through the tail of a comet, much of the debris burns in the atmosphere and forms a meteor shower.
