A million has 6 zeros, while a billion has 9 zeros, and a trillion has 12 zeros. Big numbers like vigintillion have as many as 63 zeros following the digit one. A googol is an incredibly large number with 100 zeros, and a googolplex is even larger.

How are million, billion, trillion named?

Because English took words from both Latin and old German. "Million" comes from the Latin word "mille" which means a thousand thousand, or 1,000,000. The word billion then comes to mean a million squared, or 1,000,000,000,000 and trillion, a million cubed, or 1,000,000,000,000,000,000.
