With 400 billion Milky Way stars, we estimate they contain 1-to-10 trillion orbiting planets, total.

The Milky Way is just one of hundreds of billions of galaxies.

DNRTA - is it more than 20?

1-10 trillion certainly falls within the range of what I would call "uncertainties."

I remember learning that, sadly, it's pretty unlikely that we'll ever detect a planet around another star. Even if they are there, we'll just never know.

Also the solar system has 9 planets. Get off my lawn.

The solar system has either 8 planets, or hundreds of planets, depending on what you think about Pluto. Take your pick as to the method, but either way, the number isn't 9.

It has 8 or it has at least 300, probably closer to 3,000, and maybe higher. If you're asserting Pluto is a plant but Ceres or Sedna or Makemake or Orcus or Quaoar isn't a planet then you're just making shiat up. Hell, I want to see the rational for declaring Pluto a planet but not Charon - Charon doesn't orbit Pluto, they both orbit a point in between them, which makes it a double planet.

If you read more of the article. They estimate around 10^26 in the observable universe.

We dont even know how many farking galaxies exist you worthless trashbag of a "scientist"

Dont even TRY to lie to us and say we have an accurate count on the number of planets in the universe

You have to pick a definition other than "I want it that way". That's how a religion or a cult does things, not science.

Want Pluto to be planet? Then so must be Eris, and Haumea, and Makemake, and Sedna, and all the other similar spheres of rock and ice floating out in the Kuiper belt.

Want those other lumps of rock and ice to not be planets? Then neither is Pluto. Being the first one we found doesn't make it special to the universe at large.

Pick your definition.

More like the snowflake on the tip of the iceberg.

It's not about if they're there
It's about getting there.

We're a child on a tricycle who hasn't even gotten out of our own backyard yet.
Looking out through the knot hole of the fence.

Amazing how many presume
Including many scientists

So much more to look forward to...

This is why I want to live long
To see as much as I can in my brief time of what we discover and accomplish.

If we don't kill ourselves.
Or get REALLY unlucky. (including pandemics, asteroids, etc)

Gotta be in it, to win it.

There are ~1025 planets that orbit stars, with some ~1026-1030 additional starless planets.

And in a few years they will revise that number upwardly by massive orders of magnitude.

Or a double something else. They're two mopeds away from being a picture in the Guinness Book of World Records.

Well them, congrats on achieving the coveted status of "not even wrong". Takes some effort to hold an opinion that incoherent. You do you, I guess.

according to the all wise Earthlings, Planet Earth is the only place in this vast Universe that has intelligent life.   IF life exists elsewhere in the Universe it is stupid one celled idiot bacteria that can't fly circles around our best Fighter Jets with impunity.

Just FYI Farkers who hate crypto:

there are approximately 10 to the 77th power number of atoms of all matter (called the Eddington number)  in our visible Universe.  there are also approx. that number of available Bitcoin private keys.   so no, if you're private key(s) never sees the internet (hard wallet) then no one will ever be able to find them.Have a nice day!

How stupid do you have to be to think something with a margin of error in the billions is "accurate"

Depends on the quantity being estimated.

10^9±10^9 ain't too good

10^26±10^9 is pretty goddamn accurate. Hell, even 10^10±10^9 is a useful quantification.

He didn't say that. He said within the observable universe. If it's observable, it's countable and they have been using Hubble and a bunch of other observatories for a long time learning how to estimate. Just like the US Census estimates population in the US instead of physically counting every person.

Bigthink is clickbait for people who like science.

No we don't.

From my understanding, our conceptions of universe age, distance, matter, and many other important parameters have changed a good deal in the last decade. We even know now that a lot of the universe we are seeing is entirely inaccessible, even at the speed of light. And what we think might exist now might be entirely different from what ACTUALLY exists now, as if that even matters because we will never get to it, see above.

Ahem. I am not anti-science by any means, but ... I have become wary of guys who put on a labcoat and go on YouTube or start a blog and start talking science as though it is all settled, UNTIL NEXT WEEK when they report something NEW from a NEW STUDY.

Some stuff is fun to think about. Almost all of it is conjecture and speculation, with a scientific basis that is worth examination. To me, the speculation is uninteresting. And the scientific basis is interesting, but not changing every week.

And besides, who seriously wants to fight over some "count of planets" on a wholly conjectural basis? Because it will help us "solve" the Drake equation? Please. Playing fudgy numbers is not going to give us truth. Let's fire up that telescope and look at what we can before we start thinking about all that we can't.

We don't even know how big the universe, how do you extrapolate?
