AI Thread Summary
The discussion focuses on calculating the Moon's perigee and apogee distances in relation to Earth, specifically whether these distances remain consistent with measurements from Lunar Laser Ranging (LLR). It acknowledges the precise knowledge of the Moon's orbit size and its gradual increase over time. The user seeks existing software or resources that can provide accurate data for these calculations, expressing a need for more precise orbital data. They indicate a willingness to develop their own program if necessary. The conversation emphasizes the importance of understanding any potential periodic distance anomalies in the Moon's orbit.

I want to calculate whether the perigee / apogee of the Moon always takes place at the exact same distances (radius to Earth) as measured by the LLR (Lunar Laser Ranging).

I trust that we know the size of the orbit of the moon very exactly, and also that the orbit is growing larger.

But I want to check whether calculation of the perigee / apogee happens the exact same distance as measured, to test if there should be any (periodical) distance (radius) anomaly.

My questions are;
  • Is that already done?
  • Does it already exsist such software?
  • Who is into that “business” ?

No, I am looking for a much more accurate orbit data of the Moons orbit, I think I have to program it my self
All advise are welcome.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
