Our Universe

[Maddolis]

I dont know if i should believe it or not, but for now, ill say no due to lack of proof that planets could actually be that big.

Aye, planets can't be, but stars can.
...that being said, yes it is hard to believe.
I can imagine (using Mike's scale) the sun being 11mm in diameter and VY Canis being 2.5 metres in diameter (which'd still be thousands of times bigger), but 214.5 metres is pretty crazy.

Just did the math. If earth was the size of a grain of salt (1/10th of a millimeter or 1/32 of an inch), the largest star shown there, VY Canis, would be 2.5 km or 1.5 miles wide.

In the same scale, the sun would only be 11 millimeters (or about half an inch) wide.

Thanks for that, I can almost wrap my head around it.

Edit: Actually it's 214.5 metres in diameter, not 2.5km (assuming VY Canis Majoris is 1950 solar radii) in comparison to our Sun being 11mm in diameter.
The Earthun 1/10mm : 11mm ratio is correct.

But then that last picture, that star must be billions of light years away not to be seen by the naked eye if it's that big?

It is located about 1.5 kiloparsecs (4.6×1016 km) or about 4,900 light years away from Earth.

Considering the sun is 0.00001585 light years away from earth (on average), 4900 light years is quite a while away.
