I think Phil's last sentence before the recap is a very important one. "Having to rewrite the books of sience - again." (not exactly what he said, but that's the message) is actualy what makes science so credible to me. Science isn't afraid of admiting and correcting mistakes and missinterpretations. Science, the accumulation of knowlege, is an ongoing process.

If I had to take my guess they might want to define is solely on if the planet achieved any form of Deuterium or Lithium ignition. If they were able to achieve either of those ignitions but fail to ignite Hydrogen-1 fusion they should be classified as a brown dwarf. Also these changes should be picked up in the planets spectra as it should have less than the estimated amount of Deuterium or Lithium given mass and estimated compositions of its neighbors and other factors (ex: binary system). Any other object that has not achieved those requirements could be classified as a moon system (A system with no central star but a high mass planet with moons). Note: This is given that if we can detect these types of ignition. So here are my system types. (System types: Planet Moon; no central star / Dwarf System; no central star but Dwarf ignition / Star Dwarf System; central star with a dwarf's ignition binary / finally Star System; Central Star no dwarf ignition) I have never understood the birth argument all that much so if someone could clear it up for me I would appreciate it. Have a nice day. :)

Why don't they just make anything massive enough to fuse anything at all a star? if it runs out of the fuel and dies then isn't it the same as any non explosive dead star?

@@nigelkendall5892 technically Jupiter can be classified on that scale as a Y dwarf just no one really does since we now are quite sure Jupiter formed as a "planet". Of course it gets messy since we also now know of at least one true star that likely formed as a planet given the extreme mass ratio difference between it and its "parent star" and a significant number of "brown dwarfs" around more massive A type stars almost certainly based on population dynamics formed as planets becoming massive enough to fuse deuterium and there is even evidence for some sub Jupiter mass objects probably having formed like brown dwarfs. Really just like the iffy boundaries between planets, moons, and dwarf planets we will either need to give up our discrete orderly categorization schemes for a spectrum probably based on mass and density separate from orbital parameters i.e. whether its free floating orbiting a star or another body that itself is orbiting a planet making the latter a separate categorical identifier. If up to me I would probably start with redoing the classifications of asteroids and comets separating out rubble piles from "real" asteroids like Psyche, Hygiea, Pallas, and Vesta (or similarly massed Moons like Mimas, Enceladus )or from the smaller gravitationally differentiated dwarf planets like Ceres Sedna Orcus, Haumea, Makemake in addition to similarly massed Moons Charon Dysnomia, Tethys Then the order of magnitude larger dwarf planets and major Moons that are able to support internal dynamics or even atmospheres but aren't quite massive enough to be able to support a dense enough atmosphere to support surface oceans; Pluto, Eris, Triton, Europa, Moon/Luna, Io, Callisto, Titan and Ganymede, the latter 3 are very close to the limit for the next category hence why it is really a spectrum. Next would come a category for the true terrestrial planets with well defined surfaces able to theoretically support liquid water(i.e. even Mercury if it wasn't so close to the Sun were it given an atmosphere and water should be able to hold onto it). Then would come sub giant planets(no solar system examples), ice giants gas giants, brown dwarfs and the spectral classes of stars with an additional extension to cover the WNh stars which never appear on the main sequence proper as currently defined as the vigorous CNO cycle fusion stirs up their interiors allowing them to become fully convective again and thus allowing them to fuse all their hydrogen examples including R136a1 the most massive star known at 315 Msun which is still fusing hydrogen but more than half of its way through Hydrogen burning as it's spectrum shows it is about 40% Hydrogen and 60%Helium+trace Metals. A system based off Mass and radius and thus average density using readily observable properties seems more appropriate such that at some point something like it will come into existence.

In a free-roaming spaceship simulator game, called Elite: Dangerous, you can use a "fuel scoop" to orbit around stars and gather fuel to power your ship. The acronym for the classes of stars which can be scooped is KGB FOAM. Just thought that was somewhat interesting. Have to plan your route carefully to make sure there are scoopable stars on your path or you'll get stuck in a sea of dwarf stars and be stranded. The game boasts a 1:1 scale galaxy (really! there are around 400 billion star systems!) it could take a long, long time before another player could bring you fuel. At that point it's almost better to self-destruct!

There were even planets found orbiting pulsars (neutron stars)!

Gregory Barber A star is a star, one of the bright spots in the sky. Stars normally have atomic fusion reactions going on, mostly with hydrogen fusing into helium. What we're learning is you need a certain amount of mass to fuse hydrogen. Oddly, you need somewhat less mass to fuse helium into something else. It seems some of these small borderline objects have enough mass to fuse helium, and get rather hotter than if they were just planets, but not enough to start fusing hydrogen. Physically, I gather, they're about half as big again as Jupiter, and weigh (let's say) between 50 ~ 100 times as much.

okay. I just looked up the stellar fusion chain and learned something new. I originally thought that stars fused two deuterium or one tritium and hydrogen to make He4 directly, but it turns out that the two H1 fuse giving off a positron (anti-particle of an electron) and a neutrino creating H2. then that fuses with another H1 to create He3 then two of those fuse creating He4 and giving off two more H1 atoms.

Hey CrashCourse team. Why doesn't CrashCourse astronomy have as much animation as for example CrashCourse anatomy? Thanks for the reply in advance .

SciAm14 There are several reasons for this, but the biggest is that one of the perks of doing Astronomy is that there are already a ton of awesome, free resources available in the way of images and videos, produced by organizations like NASA, ESA, ESO, etc., etc. We like being able to put our own Crash Course spin on things, and Thought Café is absolutely brilliant when it comes to taking complicated ideas and visually displaying them in ways that are easy to understand, BUT there's also no point in reinventing the wheel if we don't have to, you know? And when we start talking about stuff like planetary nebulae? Actual images are totally where it's at because they're just plain gorgeous. (Plus, I highly recommend poking around the photo/video credit links. The wikipedia links are only so-so, but anything that links back to one of those major organizations likely has a ton of additional information on something that was maybe only a small portion of our episode. There's always so much more to learn!) -Nicole

Baynard's Star? Really? The distance/year error is not the only issue with that graphic.

I'm surprised that among that animation for the theory of putting more mass into Jupiter didn't involve a monolith or the Discovery
