It is about 0.949 times Earth's radius.
If you are a believer, then God did but if you are not, then nobody did. The radius of the earth existed and therefore ots radius did before there was any form of life on earth to invent it.
Venus' radius = 0.95 of Earth's
Venus' mass = 0.815 of Earth's
Europa: 1561 km radius
Earth: 6371 km radius
The diameter is twice the radius.
Mercury's radius is 0.3825 that of Earth
Jupiter's radius is 11.209 that of Earth
So: (0.3825/11.209)*100 = 3.41 percent.
