Question

How many planet Earth's would we need for plane Earth to be the size of the planet W Cephei?

Answer 1

Well, W Cephei's solar radius is 1600-1900 (since it's considered a star).

1 solar radius is approximately 695,500 kilometers (432,160 miles), or about 110 times the radius of the Earth, or 10 times the average radius of Jupiter.

So take 1600* 110= 176000

Divide that by the Earth's actual radius which is 6,378.1 km

So it would take 27.594424671924240761355262539001

or 28 Earth's to make up planet W Cephei.

Answer 2

I don't know.

All I can say for certain is, in order to determine that, I would have to look up both of their exact diameters, and then get out a calculator.

So, we may never know.
