very cool. how did they know the name of it?

[–] humanspiral@lemmy.ca 2 points 4 hours ago

My dog Enaipo wants to hump it, and it looks a bit Russian. He named it.

We didn't know this before we had the James Webb telescope. Now we have enough resolution to read the name tags.

When I play a space game, there usually is a nametag above every planet.

If you don't see it, go to your telescope preferences, ui overlay settings, enable nametags.

(didn't read the article, yet)

Would be neat if this was the mysterious planet 9 and it was flung out of the solar system by Jupiter during the formation of the solar system. Could a planet realistically travel 47ly away in the time since the solar system formed? 🤔

If I recall, the earth is 4.5 billion years old?

So if that planet was traveling at about 1/billionth the speed of light, it could be nearly 47 light years away now.

I think that's roughly 1000km/h which sounds perfectly achievable considering we orbit the sun at 67,000km/h.

4.5 billion divided by 1 billion is 4.5. You're off by an order of magnitude.

Also, there is a lot of stuff we can see within 47 light years. Stumbling across a planet that was ejected from our solar system is highly improbable, but even less so is that planet being captured by another star and having a stable orbit. Not impossible, mind you, but the lottery is a safer bet.

With upcoming space telescopes in the 2030s, there should be a few capable of analyzing exoplanet atmospheres. Exciting to think we may be soon able to deduce the presence of carbon-based life in another planetary system.

I’ll be very happy when we discover with a high degree of certainty Earth-like planets. It will give humanity something to set its sights on. First probes then humans. Probably generational ships. All kinds of cool technology will need to be invented to enable that. I feel humanity needs a new space race.

Sorry, best we can do is multiple genocides, and bringing back viruses we've all but eliminated.

I wonder how they have discovered the name though. /j
