This one won’t hit us either, which is a good thing, because it would make quite a mess if it did. Largest Planet-Killer Asteroid To Approach Earth This Month Arriving On Saturday.
The incoming asteroid, 163373 (2002 PZ39), is 990 meters in diameter traveling at about 15,200 meters per second. Which is enough to do crazy damage.
That’s big enough to trigger a nuclear winter and mass extinction events on Earth following a collision will intersect the planet’s path this weekend.
the good news is that it will miss us by about 5,775,000 kilometers.
While I don’t like to feed the ignorance of actual measurements crowd, consider that a 9mm bullet from a typical pistol travels about 338 meters per second. (Depending on load, bullet weight, barrel length, etc.) And that bullet is SO much smaller than asteroid 163373 (2002 PZ39).
NASA has warned about these kinds of asteroids.
If 163373 (2002 PZ39) hits the planet, its initial blast would instantly kill off millions.
Then, due to its size, the energy from its explosion would be enough to trigger a global nuclear winter that could last for years. The harsh environmental changes triggered by the asteroid’s impact could lead to the mass extinction of different species.
If you want to save the planet, you should be worried about doing something to defend against these kinds of collisions. Because the next one will happen eventually.
Sweet Meteor of Death‘s 2020 campaign slogan is “Just End It Already.” Which given how long the Presidential campaign has gone on, I can understand.
And for those of you who say “I don’t like the metric system,” consider that the OFFICIAL definition of an inch is that 1 inch = 25.4mm. That is the only definition you will find for the current inch. Meters (millimeters, kilometers, etc.) are defined so that the speed of light in a vacuum is exactly 299,792,458 meters per second. So even if you are using inches, the basis for your measurements are the metric system, or the International System of units.
