How Does Solar Wind Influence Planetary Orbits?

TL;DR

Solar wind exerts a consistent but minimal photon pressure on planets, gradually affecting their orbits over billions of years. While this effect is too small to be observed in the short term, it does contribute to orbital changes and has measurable impacts on smaller bodies like asteroids through the Yarkovsky effect.

Questions & Answers

Q: Are cosmic ray observatories operational?

Yes, ground-based, space-based, and balloon-based cosmic ray observatories have been active for over half a century, aiding in studying high-energy cosmic particles.

Q: Can we detect the reflection of oceans on exoplanets?

Techniques like rotational mapping and specular reflection offer potential ways to detect oceans on exoplanets, providing insights into habitability and liquid water presence.

Q: How does the sun's photon pressure affect planetary orbits?

While the sun's photon pressure can influence planets' orbits, the effect is minimal and slow, mainly observable in phenomena like the Yarkovsky effect on asteroids.

Q: Could sending nuclear weapons to the sun cause catastrophic solar flares?

Sending all nuclear weapons to the sun wouldn't trigger solar flares; instead, they'd be consumed harmlessly, as the sun's inherent energy dwarfs any human-made input.

Summary & Key Takeaways

• Cosmic ray observatories observe high-energy particles passing through Earth's atmosphere, aiding in understanding these extreme events.
