I am so sorry for the long period of nothing and replying so late! I’ve been caught up in AP classes and all, but I want to continue to make time for this blog because I just love my followers and this blog so much <3
Anyways, to answer your question, star maps are very useful for tracking meteors. If you have a star map booklet but don’t want to scribble on the pages, you can make a copy of it or print out a segment of the sky online. Trace all the radiants onto the paper, and the majority appearing to come from Perseus can be assumed to be Perseid meteors, since sporadic meteors tend to have low activity, being few and far between. In the end, it’s all a game of assumption and a sporadic one might fool you into thinking it’s a Perseid meteor.
Hope this helps, and feel free to ask again if I didn’t quite answer you! And thanks for your great question! :)
That’s a very good argument you have, other clever minds like you have thought the same. I once saw someone argue that Jupiter, the largest planet, technically hasn’t cleared it’s orbit because of the Trojan asteroids. Earth hasn’t cleared it’s orbit because of 3753 Cruithne. But they made an exception for objects that a planet can never collide with due to orbital resonance.
However, if you are arguing that there are small bodies that Earth can collide with out there, then you are correct. There is, but you have to understand that Earth’s mass is far greater than all of the near-Earth objects combined. Pluto, however, is not greater than the mass of all its near-orbit objects.
Your argument is strong, but sadly a lot of factors play in that doesn’t make it a easy matter. For now, under current rules, Pluto is not a planet.
That’s a really good question, and the simple answer is that a hypernova produces way more energy than a standard supernova. Supernovae are known as being bright explosions from massive stars, and their remnant is usually a neutron star.
Hypernovae, however, more commonly produce black holes due to being from stars more massive than those that cause supernovae. Often time, they appear brighter too, which is why an alternate name for hypernovae is “superluminous supernovae”. Hypernovae are sometimes also the cause of gamma-ray bursts, a dangerous release of energy so high that it will fry anything in its path.
Thanks for asking! :)
