Four large craters on the Moon // Wilco Kasteleijn

From top to bottom left: Arzachel, Alphonsus, Ptolemaeus, and Albategnius.

Arzachel crater is named after the Arabic instrument maker Abū Isḥāq Ibrāhīm ibn Yaḥyā al-Naqqāsh al-Zarqālī al-Tujibi (1029 - 1100). His Latinized name was Arzachel, meaning "the engraver." He wrote books about constructing instruments for calculating the positions of the planets.

Alphonsus crater is named after King Alfonso X of Castile (1221-1284). He was sometimes nicknamed the Astrologer for the creation of the Alfonsine tables used to compute the position of the planets.

Ptolemaeus crater is named after the Greek philosopher Claudius Ptolemy (c. 100 - 170). Among his many accomplishments is the Almagest, the earliest surviving complete book on ancient astronomy. It also provided mathematical "proof" for the geocentric nature of the universe.

Albategnius crater is named after Abū ʿAbd Allāh Muḥammad ibn Jābir ibn Sinān al-Raqqī al-Ḥarrānī aṣ-Ṣābiʾ al-Battānī (bef. 858 - 928), one of the greatest and most famous astronomers of the medieval Islamic world. It was the accuracy of his data that later led Nicolaus Copernicus to consider a heliocentric model of the universe.

Relación diámetro-profundidad en los cráteres de Marte

El conjunto de datos con el que me gustaría empezar a trabajar es con el diámetro de los cráteres de marte, me gustaría conocer si tiene relación con la profundidad de los mismos.

La pregunta de partida es: ¿qué relacion tiene el diámetro de un cráter con su profundidad?

Mi hipótesis es que depende mucho del impacto que ocasionó la formación del cráter.

Según la bibliografía, para obtener una variedad de cráteres, se debe considerar la velocidad del proyectil, el ángulo de choque y la estructura tanto del proyectil como de la superficie.

I know that this absolutely wasn’t the point of your post but I’m just here to second the Disney film Crater— my parents have Disney+, and I watched it with my younger siblings at their house. In regards to cinematography and sets, it’s a really beautiful film, but also in regards to storytelling. And it’s got a lot more depth than I’m used to seeing from family friends films — my seven year old sister was equally enthralled as I was, which is rare for us, since we’ve got such a large age gap. And the actors are also fantastic — it’s crazy that some of them aren’t more well-known because they did a phenomenal job. Funnily enough some of the problems w/ capitalism did play a part in the plot and were dealt with really well……. by Disney. That was really strange. But I literally can’t believe it’s off the service already; we watched it a few months ago when it had just come out?!

It was so good! I actually watched it shortly after making my post complaining that it wasn’t available on D+. It’s not often you get decent scifi for kids - let alone scifi for kids that confronts themes like existentialism and systemic inequality. It was such a good movie and I wish more people had the opportunity to watch it on a platform as big as D+.

Tycho Crater's Peak - On June 10, 2011, NASA's Lunar Reconnaissance Orbiter captured a dramatic sunrise view of Tycho crater. Tycho crater's central peak complex, shown here, is about 9.3 miles (15 km) wide, left to right (southeast to northwest in this view).
