Moon
From Reboil
The moon is the only natural satellite orbiting Earth. The moon masses approximately 1.2% that of Earth even though it has a density 60.6% that of Earth. The moon orbits with a semi-major axis of 384399 kilometers, an eccentricity of 0.0549, and a synodic period of about 29.5 solar days on Earth. The moon may be visible from Earth's surface both night and day. Whiteish light reflected from its surface regolith offers some minimal visibility for homo sapiens at night when visibility is otherwise very poor for them, making nights with a full moon seem supernatural.

History
- 1840-03-16: John William Draper took what in the 2020s was believed to be the first daguerreotype photograph of the Moon.[1]
- 1851: John Adams Whipple and William Cranch Bond win a prize at the 1851 Great Exhibition in London for a daguerreotype of the Moon.[2]
- 2022-03-04: An unknown object, identified as a rocket booster, crashed into Hertzsprung Crater on the Moon.[3]
- 2023-02-23T20:14:30.8+09: A meteor impact is witnessed by Daichi Fujii, curator of the Hiratsuka City Museum, in Kanagawa Prefecture, Japan.[4][5][6]
Baltakatei history
- 2023-04-15: Looked up references for when the first daguerreotype of the moon by John Adams Whipple and William Cranch Bond was displayed at the 1851 Great Exhibition in London which ran from 1851-05-01 to 1851-10-15. Later, earlier daguerreotypes of the moon were discovered, namely one by John William Draper.[1]
- I looked up some equations in Explanatory Supplement to the Astronomical Almanac (1992) that can be used to correlate tropical years and synodic months with solar calendars (e.g. the Gregorian calendar), lunar calendars (e.g. the Islamic calendar), and lunisolar calendars (e.g. Hebrew calendar, Chinese calendar).[7]

Archived from the original on 2020-10-17. “Draper, a physician and professor of chemistry at New York University, was the first to produce a successful daguerreotype of the moon. On March 16, 1840, he wrote in his laboratory notebook, "This evening I exposed a prepared plate to the moonbeams which had been conveyed by a double convex lens." In this plate, a halo-like vignette encircles the image of the moon, creating a crescent shape that evokes the lunar phases. Despite his accomplishment, Draper’s efforts received only modest recognition from his contemporaries; until recently his lunar daguerreotypes were believed to be lost.”

Using the college observatory’s Great Refractor telescope, they captured the sphere in its waxing gibbous phase on March 14, 1851. ... Whipple’s daguerreotypes won a medal for excellence at the 1851 Great Exhibition at the Crystal Palace in London, which lauded their role in starting “a new era in astronomical representation.” The views were extremely popular and drew crowds as they toured across Europe, despite scientific quibbles that the photographs were not as accurate as drawn and engraved renderings observed with the human eye.”.

It was a massive flash that lasted for more than one second. Since the moon has no atmosphere, you can't see meteors or fireballs; it lights up at the moment a crater is formed).
