- Mass is an inertial property; that is, the tendency of an object to remain at constant velocity unless acted upon by an external force.
Mass in astronomyEdit
- Earth mass and Jupiter mass are the unit used to measure the mass of a planet.
- Solar mass is the unit used to measure the mass of a star.
- In theory, a very massive exoplanet is more likely to be a gas giant, while a lesser massive one is more likely to be a terrestrial planet.
