Anytime an object whizzes past earth within the moon’s orbit, I take notice and wonder when it will return and how close will its next fly-by be. Remember back when Apophis whizzed past earth and they thought that in the future it would hit the “keyhole” which would set up its next orbit to hit earth. Now they say that will not happen. The latest close encounter was back on Nov. 7, 2011 when asteroid 2005 YU55 flew by earth within the moon’s orbit and anything that close deserves some attention. I bet you didn’t even notice. . .
Since I am called Dizzy, I may as well talk about spinning objects. I don’t mean toy tops or ballerina dancers; I mean things that spin so fast it is beyond my comprehension. Have you ever heard of pulsars? They are the crushed remnants of dead stars which send out beams of radiation from their poles. Some spin at unbelievable rates for such a great mass. The latest one discovered sends out a beam every 5.44 milliseconds which means it spins 11,000 rpms. As a star dies and after the initial expansion is complete, it starts to fall in on its self. As it gets smaller it spins faster, like an ice skater when they pull their arms in.
These objects must be unbelievably dense to keep from tearing themselves apart. It is so wonderful that in this horrific universe with such deadly things happening all the time that life was able to find a more peaceful, protected world to take hold and flourish. Now, let us hope and pray that we can keep it that way. You all have a great day now, you hear?
