Sun light traveling to earth speed

Click For Summary
SUMMARY

The discussion centers on the speed of light traveling from the Sun to Earth, which is approximately 299,792 km/s. Given that the Earth is 155,000,000 km from the Sun, the time taken for light to reach Earth is about 500 seconds. The conversation explores how the Earth's rotation affects the perceived position of the Sun, concluding that gravitational interactions, particularly the gravitomagnetic effects due to the Sun and Earth's spins, influence this perception. The concept of quadrupole gravitational radiation is also introduced, indicating a deeper understanding of gravitational effects in general relativity.

PREREQUISITES
  • Understanding of the speed of light (299,792 km/s)

NEXT STEPS
  • Research the implications of light travel time in astrophysics
  • Study the principles of general relativity and gravitational radiation
  • Learn about the quadrupole nature of gravitational radiation
  • Explore the effects of gravitomagnetism on celestial mechanics
USEFUL FOR

Astronomers, physicists, and students of general relativity who seek to understand the effects of light travel time and gravitational interactions in celestial observations.

As light travels at X km/h (pretty fast), and Earth is 155,000,000km away from the Sun, How much would the Earth have rotated from the start of the light ray from the sun to the second it hits Earth?
Another way of explaining: Looking from Earth, how many degrees would the Sun have moved in the time the light ray left the Sun and reached Earth?
Or does it point to where the sun is actually located, not it's delayed position?
I had an answer saying "The best and probably the accurate description, is that when the gravitomagnetic components due to the spin of the sun and Earth are included into the calculations, they shown that the Earth is attracted towards the actual position, not the delayed one."
Is this correct?
 
Astronomy news on Phys.org
from the article:
By evaluating the gravitational effect of an accelerating mass, I show that aberration in general relativity is almost exactly canceled by velocity-dependent interactions, permitting cg = c. This cancellation is dictated by conservation laws and the quadrupole nature of gravitational radiation.

what does quadrupole nature of gravitational radiation means[?] [?]
