Planetary mass refers to the mass of a planet, typically expressed in kilograms (kg) or in terms of Earth masses (M⊕), where one Earth mass is equivalent to the mass of Earth itself (approximately \(5.97 \times 10^{24}\) kg). The concept is important in astronomy and planetary science because it helps determine various characteristics of a planet, such as its gravitational strength, potential for holding an atmosphere, and its ability to influence nearby celestial bodies.
