[QUOTE=Penguin-Man;20294428]wait, how is it 3 times younger? [editline]04:08PM[/editline] do they mean 1/3 younger?[/QUOTE] No they mean 35m years not 66m.
ITT: druggies worship the number '420'

I read it as "Planet-Orbiting Star". I got excited.
Now if only we have the technology to get there........ :saddowns:
If it's that far away, how the hell do they determine its mass and age?
[QUOTE=Kaiwren-;20309580]Name it Steve instead.[/QUOTE] That's....actually good, I've never thought about naming planets like that. It's such a buddy name. Heh, all kinds of nice things come to mind when I think about it. "Exiting Subspace jump in 3 minutes, destination: Echelon System, Planet Steve. Welcome and enjoy your stay"
[QUOTE=Snake31;20321397]If it's that far away, how the hell do they determine its mass and age?[/QUOTE] Mainly Spectroscopy, Astrometry and a few other science fields.
Always cool to find another planet out there. :v:
[QUOTE=Snake31;20321397]If it's that far away, how the hell do they determine its mass and age?[/QUOTE] They find the diameter of the star through trigonometry (measure the star at different points in the Earth's orbit, makes a triangle, you can find the diameter) From this you can find the volume. Through spectroscopy, you can find the composition of the star. Using the volume and composition, you can find the mass. Now, when the planet orbits the star it causes it to wobble slightly. By measuring the size of this wobbling motion you can determine the mass pulling on it, and so hence the mass of the planet. Now can someone explain how they find the age of the planet, because :iiam: to me. [editline]02:31PM[/editline] Give me informatives.
Relatively-young age for a planet. 35 million years is pretty bloody young in geological time.
For comparison purposes, the Earth is about 4.5 billion years old.
This is important because....
[QUOTE=The mouse;20322331]This is important because....[/QUOTE] because it's fucking interesting
When you think about it, that planet was born around the time dinosaurs went extinct (give or take few million years). Pretty cool thought.
[QUOTE=PLing;20322419]When you think about it, that planet was born around the time dinosaurs went extinct (give or take few million years). Pretty cool thought.[/QUOTE] It's 35 million years old. Dinosaurs died 65 million years ago. :eng101:
[QUOTE=DainBramageStudios;20322455]It's 35 million years old. Dinosaurs died 65 million years ago. :eng101:[/QUOTE] Give or take a few million years. Also, no one is exactly sure when the dinosaurs went extinct.
How many more times does it have to be bigger than Jupiter before it can stabilize a fusion reaction in it's core? it'd be an awesome thing to see.
Apparently if Jupiter was about 13 times more massive it would have turned into a brown dwarf
[QUOTE=Invulnerable;20322612]Give or take a few million years. Also, no one is exactly sure when the dinosaurs went extinct.[/QUOTE] Yeah, but not by a margin of 30 years.
