Answer inside
Scientists measure the mass of a gas planet by observing its gravitational pull on other objects. They calculate this using Newton's or Kepler's laws, which relate the object's orbital distance and period to the planet's mass. For distant exoplanets, they measure how the planet's gravity causes its host star to wobble.
