On average, around 10-11 years old.
About 10 years.
The average penis size for a 14 year old is about 4 inches. HOWEVER, the age at which puberty typically begins is anywhere between 10 and 15 years old. So the penis size for a 14 year old can range from prepubertal (About 2 inches) to Adult (6+ inches). At 14 years old it would be normal to have a penis anywhere in that range.

If you are 10 years old, your penis is the size that it should be. i would say about 2 1/2 to 3 inches

A 10 year old would be 10 earth years old or `0.12 Uranian` years of age. Uranus takes 84 years to orbit once around our sun. An 84 year old on Earth is a one Uranian year old.
It is unlikely that it is the exact same size, but it shouldn't have grown much. Boys' penises grow very little until they start puberty, so the penis of a prepubescent 10 year old would look very much like a 6 year old or a 3 year old. Once he starts puberty his penis will start to grow rapidly, and within a few years will become nearly adult in size.
We don't know. Some men have an 8, 9, 10 inch penis. Very seldom bigger. We can't say how big your's will be.
