Earth orbit vs. changing mass of Sun

Click For Summary
SUMMARY

The discussion centers on the impact of the Sun's mass loss, quantified at -6 x 1011 kg/s, on Earth's orbit. Over a billion years, the Sun will lose approximately 0.07% of its mass, which is insufficient to significantly alter Earth's orbit from circular to elliptical. The negligible mass loss will not produce a noticeable effect on Earth's climate. Additionally, the daily influx of meteoroids, totaling around 100 tons, contributes only a millionth of a percent increase to Earth's total mass over billions of years.

PREREQUISITES
  • Understanding of celestial mechanics
  • Basic knowledge of astrophysics
  • Familiarity with mass-energy equivalence
  • Concept of orbital dynamics
NEXT STEPS
  • Research the effects of mass loss on orbital stability in celestial bodies
  • Explore the implications of solar mass loss on long-term climate change
  • Study the dynamics of meteoroid influx and its impact on planetary mass
  • Investigate the principles of elliptical orbits in astrophysics
USEFUL FOR

Astronomers, astrophysicists, climate scientists, and educators interested in the long-term effects of solar mass loss on planetary orbits and climate dynamics.

What effect does the rate of decrease of mass of the Sun (-6 x 10^11 kg/s) have on Earth orbit? Will the orbit become significantly more elliptical over, say, a billion years? And if so, what effect would this have on climate?
 
Astronomy news on Phys.org
Since the sun's mass is roughly 2x10^30 kg, it will lose roughly .07% of its mass in its lifetime. Not enough to make a noticeable difference.
 
Welcome to PF, Dorje!

...and then there's the 100 tons of meteoroids that enter the Earth's atmosphere each day...still only a millionth of a percent increase to the Earth's total mass over the next few billion years
