It depends what you mean when you say "plus". If you mean simple addition,
the answer is 1,000,000,001,000,000,000,000,000,000
(spoken: "1 octillion, 1 pentillion").
If you mean what happens when you combine the number of place-values in one-octillion, with the place-values in one-quintillion (i.e., pentillion)? ...which technically is multiplication, not "plus"-ing... then you get:

*Centillion* Is not a measurment but is a number,1 million is 1000,000 Billion-1,000,000,000 Trillion-1,000,000,000,000 Quadrillion-1,000,000,000,000,000 Pentillion-1,000,000,000,000,000,000 Hexillion-1,000,000,000,000,000,000,000 Cept/Heptillion-1,000,000,000,000,000,000,000,000 Octillion-1,000,000,000,000,000,000,000,000,000 Nonillion-1,000,000,000,000,000,000,000,000,000,000 Centillion-1,000,000,000,000,000,000,000,000,000,000,000
A sextillion.
One octillion.
After octillion is nontillion or octillion and one. Nontillion has 30 zeros. Looks like 1,000,000,000,000,000,000,000,000,000,000
One octillion = 1027.
Billion, Trillon ,Quadrillion,Pentillion, Sextillion, Septillion, Octillion, and Nonillion
The next several in order are: quadrillion, pentillion, hexillion, septillion, octillion. Quadrillion is higher than a trillion!
17 octillion
An Octillion is 1 followed by 27 zeros. If you cut a meter into octillion pieces you would have an octillion pieces that looked like this 1/1000000000000000000000000000 A water molecule is less than one nanometer and a nanometer is one billionth of a meter. you would need 1000000000000000000 (a pentillion(or 1 followed by 18 zeros)) of the fraction above before you got to the thickness of a water molecule. It might be safe to say that nothing is this thin. Shaquille O’Neal, a very tall basketball player, is 2,160,000,000 nanometers tall

No, it is not.
A sextillion.
One octillion.
a pentillion
It's a number: 1,000,000,000,000,000,000
After octillion is nontillion or octillion and one. Nontillion has 30 zeros. Looks like 1,000,000,000,000,000,000,000,000,000,000
