How many zeroes are in a billion?

Daddy told me there are 9 zeroes in a billion. So, mommy asked me how many zeroes are in a Quadrillion and I did not know. So we asked Google.

In the US the progression is:
Hundred - 100
Thousand - 1,000
Million - 1,000,000
Billion - 1,000,000,000
Trillion - 1,000,000,000,000
Quadrillion - 1,000,000,000,000,000

Hundred has 2 zeroes
Thousand has 3 zeroes
Million has 6 zeroes
Billion has 9 zeroes
Trillion has 12 zeroes
Quadrillion has 15 zeroes

What about something more than quadrillion? We did not know, so we asked Google.

Quintillion has 18 zeros
Sextillion has 21 zeros
Septillion has 24 zeros
Octillion has 27 zeros
Nonillion has 30 zeros
Decillion has 33 zeros
Undecillion has 36 zeros
Duodecillion has 39 zeros
Tredecillion has 42 zeros
Quattuordecillion has 45 zeros
Quindecillion has 48 zeros
Sexdecillion has 51 zeros
Septendecillion has 54 zeros
Octodecillion has 57 zeros
Novemdecillion has 60 zeros
Vigintillion has 63 zeros
Googol has 100 zeros
Centillion has 303 zeros (except in Britain, where it has 600 zeros)
Googolplex has a googol of zeros

Our solarsystem which has sun, earth and other planets is 4.5 Billion years old.
