The NASA JPL Center for Near-Earth Object Studies now lists the YR4 asteroid impact probability as 0.00005 (0.005%) for its passage by Earth in 2032. That is impact probability zero!
Okay, thanks, that works for me.

This earthly existence is getting increasingly expensive, but at least we do get a free trip around the sun every year! Our sun, the only star in the solar system, is truly amazing! It's orbited by eight planets, at least five dwarf planets, tens of thousands of asteroids, and perhaps three trillion comets. It holds everything together with it's gravity, keeping Earth, you, me, and generally all sort of things in its orbit. . . . . . . . And here is the first question: WHAT TYPE OF STAR IS THE SUN? . . . . . HINT: It is not a White Dwarf... yet.

HOW OLD IS THE SUN? . . . . . HINT: The Sun is a G-type main-sequence star (G2V). These stars live for about 10 billion years, and our middle-aged sun is about halfway through its lifetime. Still not celebrating!

Our Solar System is nestled inside the Milky Way galaxy and is encased in a bubble created by the sun, which separates us from the galaxy's harsh space radiation. THIS BUBBLE (outer atmosphere of the sun ) IS CALLED? . . . . . . HINT: God of the Sun in Greek Mythology.
I don't know, and I'm not celebrating!
