SUMMARY

The discussion centers on calculating the mass of a theoretical planet that orbits a star with a mass of 1.07 solar masses and a radius of 1.05 solar radii, located 1.08 AU away with a period of 400 days. Participants concluded that it is impossible to determine the planet's mass without an orbiting satellite or additional data. The necessary formulas for mass calculation, such as those involving gravitational interactions or Kepler's laws, were not provided due to the lack of sufficient information.

PREREQUISITES
  • Understanding of Kepler's laws of planetary motion
  • Familiarity with gravitational force equations
  • Knowledge of stellar and planetary characteristics
  • Basic concepts of orbital mechanics
NEXT STEPS
  • Research Kepler's Third Law for mass determination
  • Study gravitational force equations for celestial bodies
  • Explore methods for estimating planetary mass without satellites
  • Investigate the relationship between a star's properties and its orbiting planets
USEFUL FOR

Astronomy students, astrophysicists, and space science enthusiasts interested in planetary mass calculations and orbital dynamics.

Homework Statement


Hi I am doing a report for a space science class, and i have a theoretical planet that orbits a star 1.07solarM 1.05solarR 6000K, then planet is distance 1.08AU, a period of 400days, temp of 12.85degC and radius of 1.98earthM... Is it at all possible to find the planets mass!? if i don't have an orbiting satellite? if so could you tell me the formula, i can't find one anywhere...

No, we can't find the planet's mass from the information given.
