Sun's Mass
The Sun's mass (M_sun) is a standard unit of mass used in astronomy to express the mass of other stars and celestial objects, approximately equal to 1.989 × 10^30 kilograms.
History/Origin
The concept of using the Sun's mass as a unit originated in the early 20th century as astronomers sought a convenient standard for stellar masses. It became widely adopted in astrophysics for its practicality and ease of comparison.
Current Use
Today, M_sun is commonly used in astrophysics and astronomy to describe the mass of stars, planets, and other celestial bodies, facilitating standardized communication and calculations within the scientific community.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
