[astrogeology] measuring atmospheric density

Click For Summary
SUMMARY

The discussion centers on the equation for density expressed in units of g/cm³, which represents mass per unit volume. Participants explore its application in measuring atmospheric density on celestial bodies, specifically Saturn's moon Enceladus. The conversation highlights the gravitational influences from Saturn and its moons as factors in atmospheric density calculations. The origins of the density equation are questioned, emphasizing the need for clarity on its derivation and application in planetary science.

PREREQUISITES
  • Understanding of basic physics concepts, particularly mass and volume.
  • Familiarity with gravitational effects on celestial bodies.
  • Knowledge of planetary atmospheres and their composition.
  • Basic mathematical skills to interpret equations and units.
NEXT STEPS
  • Research the derivation of the density equation in physics.
  • Study the gravitational interactions of Saturn and its moons.
  • Explore atmospheric density measurements on other celestial bodies.
  • Learn about the composition and characteristics of Enceladus' atmosphere.
USEFUL FOR

Astronomers, planetary scientists, and students interested in astrophysics and atmospheric studies of celestial bodies.

Can someone explain the equation g/cm^3 in layman's term? I was reading up on this article on Saturn's moon Enceladus, having heat, and the first thing i though was the gravitational tuggin from Saturn and it's other moons. And i came across this equation and seem like it's used to base density levels of atmospheres on planets. Also how did they come up with this equation?

noone, eh?
 
\rm{g}\over\rm{cm}^3 is the units for density, which is the mass per unit volume.

Not sure what you are asking here. Are you asking how they derive the atmoshperic density of the planets, or how they came up with the equation for density? I can't see where they have used it in the article either.
