Los planetas enanos del Sistema Solar https://lasendadeapolo.es/2021/09/25/los-planetas-enanos-del-sistema-solar/ Tras intensos debates en la comunidad astronómica mundial y a pesar de las protestas de muchos aficionados, el 24 de agosto de 2006 Plutón dejó de ser un planeta y pasó oficialmente a ser un planeta enano. Mientras se acaba de zanjar la polémica, este cautivador mundo helado se ha convertido en la primera etapa de una nueva época de descubrimientos en los confines del sistema solar.
Hace casi un siglo, el 14 de marzo de 1930, periódicos de todo el mundo se hacían eco del descubrimiento de Plutón con titulares como este: “Descubierto el noveno planeta al borde del sistema solar: el primero encontrado en los últimos 84 años”.
Su clasificación como planeta se mantuvo durante décadas, pero j el 24 de agosto de 2006, pierde ese estatus y pasa a ser clasificado como ‘planeta enano’, tras un encendido debate en la XXVI Asamblea General de la Unión Astronómica Internacional (UAI) celebrada en Praga (República Checa) y la subsiguiente votación: 237 votos a favor del cambio, 157 en contra y 17 abstenciones.
Pocos acontecimientos han dividido tanto a la comunidad astronómica mundial, tanto aficionada como profesional, como la reclasificación de Plutón. Sin embargo, este tipo de reclasificaciones de objetos una vez que se ha comprendido mejor su naturaleza no es ajena a la historia de la propia astronomía.

"Impact cratering happens on every solid body in the Solar System. In fact, it is the dominant process affecting the surfaces on most extraterrestrial bodies today.

On Earth, however, such craters are often lost over time by active geological processes, but elsewhere in the Solar System there are some truly majestic examples of impact craters preserved for all to see.

Here, we pick our highlights of what the Solar System has to offer." #space #craters #science #astronomy #SolarSystem #geology #astrogeology #exogeology #Moon #Mars #Ganymede #Ceres #Venus

Ceres comprises 25% of the asteroid belt's total mass.

A preview of what #UranusOrbiter and Probe might find in the 2040s
The #water is believed to be located between the core and icy crusts in oceans 30km deep for moons Ariel and #Umbriel, and less than 50m for #Titania and #Oberon.
It's not uncommon to find water in dwarf #planets and moons. For example, #dwarfplanets #Ceres and #Pluto, as well as #Saturn's moon #Mimas, have all shown evidence of liquid water.

According to a new report by Ceres, a sustainable-finance research and advocacy group, banks have a climate problem. The report evaluates the climate plans of six major U.S. banks and finds that none of them are aligned with the 1.5°C goal of the Paris Agreement. The report also urges banks to adopt absolute emissions targets, disclose their financed emissions, and increase their green investments.

Dear Pluto,

Fuck you. I was a planet 130 years before you were discovered and they demoted me to a freakin' asteroid, but you don't see me being a whiny little bitch about it.

Sincerely,
Ceres (The Dwarf Planet formerly known as Asteroid #1)

Here is my attempt of the #Ceres #Messier100 appulse collected with T18 from iTelescope.net. The background image is a color stack of all the data. I then made frames using B&W images on top of the color background to show Ceres moving.

https://hendric.smugmug.com/Hobbies/Astronomy/ITelescope/Ceres-M100/i-qWWcMRn/A is just the B&W images.

https://hendric.smugmug.com/Hobbies/Astronomy/ITelescope/Ceres-M100/i-vt5x6S2/A is a movie of the 4 full color frames.
