Thousand trillion = 1,000,000,000,000,000 which has 15 zeros in it
18 zeros 1 million = 6 zeros 1 billion = 9 1 trillion = 12 1 quadrillion = 15 1 quintillion = 18 1 sextillion =21
"Drillion" does not appear in either the American or the British system of numeration for denominations up to 10600. The closest name on either list is the "trillion", meaning '1' followed by 12 zeros (American) or 18 zeros (British). The next designation is "quadrillion". In the American system, '1' with 15 zeros. In the British system, '1' with 24 zeros.
A quadrillion has 15 zeros, so there would be 15 zeros in a quadrillion miles.

There are 15 zeros in the number 6,000,000,000,000,000 (6 trillion). ---- Actually, this is six trillion -> 6,000,000,000,000 so there are actually 12 zeros in 6 trillion.
1,000,000,000,000 is 1 trillion a 1 followed by 12 zeros a 1 followed by 15 zeros is 1 quardrillion
Thousand trillion = 1,000,000,000,000,000 which has 15 zeros in it

In the "short scale" used in the US and officially in the UK, there are 12 zeroes in "one trillion" (one thousand billion).
18 zeros 1 million = 6 zeros 1 billion = 9 1 trillion = 12 1 quadrillion = 15 1 quintillion = 18 1 sextillion =21
In countries that use the long scale (eg Europe): 18In countries that use the short scale (eg USA): 12
One million trillion billion googolplex =10,000,000,000,000,000,000,000,000,00010100 but the progression is: thousand - 3 zeros million - 6 zeros billion 9 zeros trillion - 12 zeros quadrillion - 15 zeros quintillion - 18 zeros etc, googleplex - an inconceiveably large number equal to ten times the amount of a number that would be 10 with a hundred 0's behind it, or 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
Ten-thousand trillion has 16 zeros; this is also known as ten quadrillion One trillion = 1,000,000,000,000 (12 zeros) Ten trillion = 10,000,000,000,000 (13 zeros) One-hundred trillion = 100,000,000,000,000 (14 zeros) One-thousand trillion = 1,000,000,000,000,000 (15 zeros) (or one quadrillion) Ten-thousand trillion = 10,000,000,000,000,000 (16 zeros) (or ten quadrillion) That assumes the short scale (based on powers of a thousand plus 1) where thousand-trillion is not a normal moniker for a number - it would, as the answerer points out, be called ten quadrillion. The long scale (based on powers of a million) does use the moniker thousand-...illion for numbers (which are alternatively called ..illiard, eg 1000 million = 1 milliard, 1000 billion = 1 billiard, etc). In this case: 10 thousand trillion = 10000 x (106)3 = 104 x 1018 = 1022 and so has 22 zeros.
1,000,000,000,000,000 is a quadrillion in the US and a trillion in the UK and some parts of Europe.
