The given statement can be written as below after correcting the three errors in it:
Given statement: The N.A.S.A. spacecraft is approaching Jupiter, which has a diameter more than eleven times greater than that of earth.
Corrected statement: The NASA spacecraft is approaching Jupiter, which has a diameter more than 11 times greater than that of Earth.
Corrections made:
- The name abbreviation of the name of the National Aeronautics and Space Administration is formally written and NASA and not N.A.S.A.
- The correct way of mentioning a number in a sentence is by putting it in digits (11 not eleven).
- Earth is a noun. Hence the first letter of the word should be capitalized.
