Explanation:

• Planets generally have less mass in comparison to the other three.
• A brown dwarf is a type of substellar object that has a mass between those of the heaviest gas giant planets and the least massive stars, i.e., approximately 13 to 75–80 times that of Jupiter(MJ).
• Below this range are the sub-brown dwarfs (sometimes referred to as rogue planets), and above it are the least massive red dwarfs.
• Main Sequence stars like the Sun have 1048 Jupiter masses. 
• Red dwarf stars have masses from about 0.08 to 0.6 times that of the Sun.
