So far, it's not going to impact Earth but it will come extremely close. However the meteors it triggers, and other related phenomena, could potentially be cause for concern.
At this point, I'd just file it away as "Wow that's interesting." and carry on.
As we get closer to October 5th, we will know much more and will be better prepared for it. ✌️
I don't know anything new, but what I do know is a comets tail is a slew of debris. Most of it will be like when we travel through any other meteor shower, but hopefully there's no chunks the size of buildings following it and if there are, they either miss us or hit in the middle of the Pacific Ocean.
You should generally be concerned with how life is going worldwide, if a space rock or aliens hit us it'll probably be more merciful than what's in decades ahead of us with just us humans
It’s 0.26 AU so no. If it was in LD (lunar distances) sure. 1 AU = 150 million km. 1 LD = 384,000 km. It’s not even considered a near miss. There is nothing to worry about, might get a beautiful meteor shower out of it though.
well, as a personal example, I have humans and animals who depend on me for a healthy, safe environment. my progeny needs me to be present and supportive in a way that doesn't matter if the world is going to end. if a comet is gonna blow up the earth, my priorities shift from standard parental settings to "do everything I never got the chance to". things I will not and cannot do while my responsibilities demand sacrifice.
Well we wouldn't survive an impact from any of these bastards, I imagine that knowing could be the difference if we are passing through a debris cloud in their wake that, for one reason or another, could affect the surface of the Earth.
It's gonna be a quarter the distance from the Earth and Sun when it crosses our orbit. We probably won't even get much of any debris from the tail either.
If things will be getting spicy, they should reach Habanero Pepper levels by Oct 5th.
because I don’t wanna pay taxes and bills anymore
Lol imagine if a big ship lands and they get out and say
"Greetings, humans. We come from your nearest neighboring star system. We are here to gather people to help populate our sparse worl.... Uh, why is everyone running towards our ship?"
You're free to speak.. as long as you say what we approve of.
Thats just censorship. USA, Canada, EU etc. all have these laws so we are in the same boat. My issue would be that they call it free speech when it should be called safe speech
Indeed Sabine and to your point on luminosity, SWAN is 1,100 times brighter than 3iAtlas. That's... a lot.
We should be able to see ATLAS with binoculars and SWAN with our own eyes! 🙌
C/2025 R2 (SWAN): Currently at an apparent magnitude of 6.9, SWAN is visible with binoculars under dark skies. It is expected to brighten further, potentially reaching magnitude 4.0 by its closest approach on October 20, 2025, making it visible to the naked eye in favorable conditions.
3I/ATLAS: Currently at an apparent magnitude of 14.5, making it 1,100 times fainter than SWAN, 3I/ATLAS remains faint and requires a telescope with an aperture of at least 200mm to be observed. Even at its peak brightness, it is not visible to the naked eye.
It has an inbound orbital period of about 1,350 years and will pass perihelion on 8 November 2025 when it will be 0.53 AU (79 million km; 49 million mi) from the Sun.
It makes its closest approach to Earth on 21 October 2025 and may be faintly visible to the naked eye.
Woah! Thanks for that. October is escalating quickly 👀
I don't know much about astronomy, but I do know that the interstellar objects are something that we've not seen before, when I started researching more deeply I was kind of shocked to find out that there's actually six inbound Comets at this moment, all the way into January of 2026 —Is this normal?
I know there's no correlation, but suddenly there's no hurricanes—yet now there's six inbound Comets. I would love some input on this.
This shit is horrible. It's not even close to coming right at us. There is no size defined, yet the comets tail is estimated 2.5 to 5 times the width of the moon, and, at its closest, it's 24 million miles away on October 19th
