Seven rocky, Earth-size planets have been found circling TRAPPIST-1, a red dwarf star about the size of Jupiter.
A few of the worlds might even be habitable.
The monumental discovery has prompted scientists to launch a website for the planetary system — and yes, it has an equally monumental domain: trappist.one.
Researchers inspired by the new planetary system, which is about 39 light-years from Earth, are using trappist.one to publish fiction, artwork, and even poetic prose about it.
Called “Ode to 7 orbs“, it beautifully explains the discovery and importance of TRAPPIST-1’s seven planets.
Raymond gave Business Insider permission to share his work, which we’ve reproduced here with a few illustrative additions.
Wake up now people, I've got some big news!
You won't want to miss this. You don't want to snooze
We just found some planets while we were stargazing
Gather 'round, listen up. These ones are amazing!
And it's not just one new planet. There are seven!
All orbiting one star up there in the heavens.
(With seven planets it still goes to eleven…)
The thing 'bout this system that just makes us squeal,
All seven are Earth-sized. Now, that's a big deal!
And four of those planets could have the conditions
For liquid water! (based on their positions)
Most of the stars just looked awfully boring
They stayed the same brightness. They weren't worth exploring.
The ones we were looking for had little blips
Their brightness stayed constant except for small dips
Each dip is a planet that, just as it passes
In front of the star, blocks some light from our glasses
The brightness we measure goes blip every time
The planet goes once around. Then it re-aligns.
(Another way that you can think of the dips:
Each blip is like a single tiny eclipse)
Armed with the star's brightness, we measured and figured
How big are the planets and how they're configured.
This new star with planets is called TRAPPIST-1
It's not a star that is at all like the Sun
It's much much much smaller, and also less hot
Two thousand times fainter. (Now that is a lot).
An 'ultracool dwarf' star they call it. And hey,
It's just about 40-odd light years away.
The planets have letters for names. Now, you see,
From outside to in it's h, g, f, e, d,
And, yes, as you guessed, after that, c and b
(The first one's called b. There is no planet a.
The 'a' is reserved for the star, by the way).
All seven planets are close to their star.
They orbit real fast since they're not very far
Planet b's year: one and a half Earth days.
If you lived there you'd have all sorts of birthdays!
Stand on a planet in the TRAPPIST-1 system
Oh, the planets you'd see in the sky -- you can't miss 'em!
Their orbits are so close that they'd each appear
As big as the full Moon! Bigger when they're near.
(Imagine the werewolf problem they must fear!)
The Sun in the sky would stay in the same place.
The planets always show the star the same face
The planets would shift and sometimes look like crescents
A peek at that sky's like an antidepressant!
The two inner planets, planets b and c.
Are too hot for oceans. Water would be steam.
But the next four planets: d, e, f, and g
Are all at about the right place for a sea.
They could have liquid water, although
We don't know if they even have H2 or O.
There's plenty of planets out there that are dry
Just look at that big red dot up in Earth's sky.
That's Mars, it's got water but only a trace
And Venus, of course, is a hot hot dry place
The planets' orbits were not set by chance
They seem to be following a cool cosmic dance
Take for example planets d and e
When e completes two orbits, d has done three.
They meet up again at the very same place
This orbital resonance is common in space.
Each pair of planets is in resonance. So,
It's like the whole system is doing a tango!
We think that a resonant configuration
Is a signpost of the planets' migration
That means that the planets' orbits shifted
While they were forming, inward they drifted.
One last cool thing I really want to say-o
TRAPPIST-1's actually linked with Galileo!
He discovered Jupiter's four big old moons
That you can see with good binoculars too.
The TRAPPIST-1's planets are much farther out
But take about the same time to go around.
Now let's wrap up with a ditty for later
It's written for you if you're a planet hater
'Planets', you say, 'no big deal. There's a zillion.
Eight in our Solar System and a billion
In orbit around other stars in the sky
Why should I care about this one little guy?'
I'd answer your question with a look back at history
Discovering new planets may help solve a big mystery.
Are we all alone? Is there other smart life?
(Do I have an alien doppelganger and wife?)
