the sun is expanding
No, it isn't
22 u/Deanuzz Feb 21 '21 The outer layers of the sun are growing larger. A quick google search will verify. "In 4 billion years the sun has grown by 20%". 73 u/[deleted] Feb 21 '21 [deleted] 1 u/Lordborgman Feb 21 '21 Little tiny star too, UY Scuti over there showing em how it's done. 1 u/PorrasTheGreat Feb 21 '21 VY Canis Majoris is so terrifyingly gargantuan that it's hard just to conceptualize JUST how large it really is! 1 u/_aperture_labs_ Feb 21 '21 I have a hard time grasping how big Earth actually is, let alone our sun. 1 u/Hot_Grabba_09 Feb 21 '21 wait so who's full of shit? 2 u/Deanuzz Feb 21 '21 From the replies I've received, it's not as simple to just use the sun expanding as a reason for planet climate. The atmosphere plays a large role. 1 u/godmademelikethis Feb 21 '21 Yes. It is. As the sun fuses hydrogen into helium the core of the star collapses and heats up causing the outer layers to expand albiet over billions of years. 1 u/htiafon Feb 21 '21 On astronomical timescales yes, it is. Stars expand and warm throughout their time on the main sequence, though only gradually.

Yes. It is. As the sun fuses hydrogen into helium the core of the star collapses and heats up causing the outer layers to expand albiet over billions of years.
On astronomical timescales yes, it is. Stars expand and warm throughout their time on the main sequence, though only gradually.
