body1 = input ('ENTER THE NAME OF THE FIRST CELESTIAL BODY: ','s');
body2 = input ('ENTER THE NAME OF THE SECOND CELESTIAL BODY: ','s');
planrad = input ('ENTER THE DISTANCE BETWEEN THESE TWO BODIES IN (m): ');
massbod1 = input ('ENTER THE MASS OF (body1): ');
massbod2 = input ('ENTER THE NAME OF (body2): ');
I'm asking the user to define the above variables... How can I programm "massbod1" and "massbod2" to automatically insert the user entered text?

I suspect that this is what you are trying to do
numbodies=4;
for i=1:numbodies
massbod(i)=input (['ENTER THE MASS OF (body ' num2str(i) '): '])
end

Yes it will. You just have to apply the same techniques consistently when gathering the names,
>> cbnames= input('ENTER THE NAMES OF THE CELESTIAL BODIES:')
ENTER THE NAMES OF THE CELESTIAL BODIES:{'Jupiter','Venus','Mars'}
>> massbod = input ('ENTER THE MASS OF ALL BODIES AS A VECTOR: ');
ENTER THE MASS OF ALL BODIES AS A VECTOR: [10 20 30]
Then use a loop over both to print results,
>> for i=1:3, disp(['The mass of ', cbnames{i} ' is ' num2str(massbod(i))]), end
The mass of Jupiter is 10
The mass of Venus is 20
The mass of Mars is 30

You're right - I had to read it again. Thanks for looping back to my comment!
