NASA warned of a “planetary killer” asteroid: Are we in danger? | Chronicle

Astronomers need the new asteroid very close to Earth . In a recent note to analysis, astronomers mentioned it as a planet ‘Potentially dangerous’ .

The official name of the asteroid is 1998 OR2 But, it is also known as “Killer Planet” . This is expected to happen in a few days More than 5 million km from Earth .

This new discovery will be the closest to our planet for 100 years. It must be remembered that a file last asteroid Who was so close to this world was in the year 1999 .

According to experts, the next clip from OR2 of 1998 will be many years from now, more specifically February 23, 2150 . Exact information about the size of this huge asteroid has not yet been provided, but many believe so Its measurements are similar to those on Earth . Its orbit will move to more than 5 million km, which could cause an explosion A terrible catastrophe for humanity .

To be able to see the astronomical spectacle that you would not be able to enjoy twice, there are more than one option. enter page www.virtualtelescope.eu It’s a great facility, but you may takes overengineering technology To be able to see these types of events clearly.

What does it mean for an asteroid to be “dangerous”?

considered a asteroid Potentially Hazardous (PHA) For those with the ability to quickly approach Earth, the minimum orbital transit distance must be less than 0.05 astronomical units. They should also have a file the size 22 or more and an end-to-end distance greater than 50 metres.

In a more scientific definition, PHA is “Space rocks of absolute size (H) 22.0 or less and with a minimum orbital intersection distance (MOID ) of 0.05 IU or less”.

For these sizes, these types of asteroids can cause a Of mass destruction man because of his size.

There are a number of levels to measure the severity of the phenomenon. This is known as “size Turin “ It is divided into:

• Level 0: The probability of a collision is zero or much less than the probability of a random object hitting the Earth.
• Level 1: a very low probability of collision, similar to the probability of a random object hitting the ground.
• Level 2: Low chance of collision.
• 3 . level: probability of collision capable of causing local damage greater than 1%
• level 4: The probability of a collision capable of causing regional damage is greater than 1%
• level 5: A high probability of a collision capable of causing regional devastation
• Level 6: High probability of a collision capable of causing a global catastrophe
• Level 7: Very high probability of a collision capable of causing a global catastrophe
• Level 8: a safe collision, capable of causing local damage. This should happen once every 50 to 1,000 years.
• Level 9: A sure collision capable of causing regional devastation. This should happen once every 1,000 to 100,000 years.
• Level 10 : A sure collision capable of causing a global climate catastrophe. This should happen once every 100,000 years or more.
