Comet 3I/Atlas: Still Unnamed & Other Musings

The Sky Live

The first Interstellar Object (ISO) was christened Oumuamua; the second one, Borisov. 

Since its official discovery on 1 July 2025, a good two months have already passed but this latest ISO has yet to be given a name apart from its scientific designation. This visitor has attracted so much attention because of its peculiar properties and yet it remains nameless.

Why is this so? It would be nice if someone studying this ISO volunteers a name.

Although there is still no agreement in the Scientific community about its size, there appears to be an eager attempt to drastically downplay its initial estimations ~ from a diameter of 20km (12 miles) to just a few hundred metres, although 5.6km seems to be quoted often. I've even seen Nasa reporting its estimated size by using radius instead of diameter.

I am not at all an expert on Comets and their related scientific properties, but it's obvious that 3I/Atlas' "bizarre" (they've used this term) makeup and behaviour are confusing the experts so they are trying to shoehorn this visitor into known parameter boxes.

And finally, I can't help but wonder what would happen if this visitor starts to steer away from its projected trajectory....

Namarie! 💛
