AI Thread Summary
Earendel is estimated to have a luminosity around 10^6 times that of the Sun, based on its mass of approximately 75 solar masses. It is significantly larger and hotter than the Sun, with temperatures exceeding 20,000 K, making it 3-4 times hotter. In comparison, UW Canis Majoris, while hotter at about 30,000 K, has a lower mass of around 40 solar masses and a luminosity over 330,000 times that of the Sun. The discussion highlights the extreme characteristics of Earendel in terms of size and temperature relative to other stars. Understanding Earendel's luminosity contributes to broader knowledge of stellar evolution and characteristics.

I just read an article about it, and an internet search & Wikipedia did not have this information. A rough interpretation of the HR diagram for a mass of 75 suns in Main Sequence) says it is about 106 suns.

10^6 sounds about right. It is both much larger and much hotter than the Sun, being 50-100 solar masses and more than 20,000 K, between 3-4 times as hot as the Sun. As a comparison, UW Canis Majoris is hotter, at roughly 30,000 K, but is much smaller, with mass estimates placing it, at most, around 40 solar masses. Its luminosity is upwards of 330,000 times greater than the Sun.

Thread 'Venus and Jupiter Conjunction'

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...
