The sound of 5000 exoplanets
March 26, 2022 6:35 AM   Subscribe

On March 21, 2022, the number of known exoplanets passed 5,000 according to the NASA Exoplanet Archive. The music is created by playing a note for each newly discovered world. The pitch of the note indicates the relative orbital period of the planet. Planets that take a longer time to orbit their stars are heard as lower notes, while planets that orbit more quickly are heard as higher notes.

This pushes all of my nerd buttons and I love it.

My first year of high school, there was no proof of planets outside the solar system. Five thousand seems like a lot, but maybe we have 100 billion in our galaxy, and there are as many galaxies.

It seems almost egotistical to presume we're alone.

I wonder what that cross-shaped blue cluster in the middle-left represents

More than 1,200 new planets discovered through Nasa's Kepler space telescope

The new planets were found in only a small patch of the night sky, between the constellations of Lyra and Cygnus.

Some of those exoplanets are actually brown dwarfs. I mean, if you're going to count 2MASS J01225093-2439505 b, GSC 06214-00210 b, HIP 75056 A b, USco1621 b, or WISEP J121756.91+162640.2 A b, then what definitional parameters are you even...

Eh, never mind. This is cool.

Oh sure, first dwarf planets don't get to be planets, now brown dwarfs don't get to be planets. Soon there won't be any planets at all!

Great fun!

For those who haven't encounted them, the explanet orreries are also neat. None are up to date, I think. The earlier ones may be more impressive, 'cause you can actually see the details. (I may have missed even better or more recent ones.)
