Isn’t it actually green?

@Ichijoe  
The Sun is a “main sequence” star, like almost all stars. The main sequence starts from relatively cool, small-mass stars (red dwarfs), through orange, yellow, white, and finally high-mass (and short-lived) blue giants. Non-main sequence stars include red giants (stars about to go nova) and white dwarfs (stars that just went nova).
 
The Sun is pretty much in the middle of the main sequence. It’s a slow, steadily burning orb about halfway through its expected 10 billion year lifetime. Eventually it’ll blow up into a red giant, go nova, and collapse into a white dwarf.

That is true. The sun is white but due to atmosphere around us the spectrum is indeed changed to yellow. XD SSSCCCCCIIIIIEEEEEENNCCCCCEE!!!!!!!!

I thought Stars more or less came in shades of blue (Super hot,short lived), yellow stars like Sol, and Super red giants like betelgeuse. AFIK only dead / dying Dwarf Stars get to be brown, red, or white.

The Sun is what’s called a “black body object”, whose color is directly a function of its surface temperature. At the Sun’s surface temperature, black body objects give off a spectrum of light that appears yellow to the human eye. If it were a little cooler, it would be more orange, and if it were a little hotter, it would be more white.

Fun Fact: Celestia is actually light light pink.

I like my horse women like I like my science… Accurate

There is no dark side of the Moon, really. Matter of fact, it’s all dark….

Yep that’s true

Well, presumably you don’t have that telescope located on the moon, so the atmosphere is still in between you and the sun. That was the issue. >.>

Not if you stare at it long enough V:

You should try them. Looking at the sun is pretty amazing once you get it.

It is white light but gives off mostly green.  

@OneAmongOthers  

 
RIP, your eyes.

I thought it was mostly green…

Yet when I look through a telescope at it its more yellowish than white.

oh no you’re not taking this bullshit here

Celestia is made of plasma, head canon accepted.  
@TB Tabby  
The moon makes no light of its own, it only reflects the light of the sun.

Not only is Celestia perfect, she’s scientifically accurate.

And Celestia is pastel pink.  
Luna is actually purple a bit.

@TB Tabby  
Moon is black, is why everyone hates it so much
 
BLACK MOONS MATTER!!!

Is the moon dark blue?

Wow! Me too! We must be related or something!
