How to use input command?

The purpose of these two lines is for the user to input the name the "planet", then the next question asks the mass of the planet. In the second line, I am trying to call the variable 'name' so the question in line 2 incorporates the name of the planet. However, I get an error on the second line saying "Too many input arguments". Also, I am new to MATLAB. Please help

name = input('What is the name of the exoplanet? ', 's');
massplanet = input('What is the estimated mass of %s (kg)? ', 's', name);
