You’ve probably read this week about a “planet the size of the tallest building in the world injured 56 m. M meters per hour.” Some news sites “confirm NASA.” Insert. Most of these things are technically correct, but the most important point remains.
Asteroid 153201 (2000 W107) will miss Earth by approximately 2.7 million miles on Sunday. Observations of the planet place its size somewhere between the four soccer fields. That huge size comes from the difficulty of determining the size of relatively small objects so far.
What makes me itchy is why this particular North Earth (NEO) project is getting so much attention. The NEO trio returning to Earth on Thanksgiving is even more exciting. This includes the 2018 RK Q4 planetary, which will be 10 times closer on Sunday.
Protect the planet
In 2005, Congress set a goal for NASA to find about 90% of the closest planets to Earth that are 460 feet (140 meters) or larger in size. The space agency responded to the one called NASA Center for Near-Earth Object Studies, which tracks this and other NEOs.
The next time you see a claim for a planetary ship going to Earth, you will be able to see the data for yourself. The Centre’s latest information on upcoming approaches.
The data shows a proximity (CA) of approximately 19 sandal distances (LD) over the next 60 days. Any SEO with more than one number in the “CA Distance Minimum LD” column has no chance of hitting the moon, much less the Earth.
