Include Sun's Diameter in Star Distance Measurement?

AI Thread Summary
When measuring star distances using the trigonometric method, the diameter of the Sun is not included in the baseline measurement. The baseline is determined solely by the size of Earth's orbit, which is approximately 2 astronomical units (AU). The Sun's position is considered as a reference point, but its diameter does not factor into the calculations. This clarification helps in understanding the application of parallax and Pythagorean theory in astronomy. Accurate distance measurements rely on the Earth's orbital dimensions rather than the Sun's size.

When measuring the distance of stars from the Earth using the Trigonomic method, using the parralax and Pythagorem theory, do you include the diameter of the sun with the 2 Au when measuring the baseline of the triangle?

I'm assuming yes, but not sure.

No. You're just using the size of the Earth's orbit. The Sun just happens to be (near) the center. (Ellipse, you know)
 
thnx i can see it now
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
