I cannot describe the meaning.

"Simulated appearance of Saturn as seen from Earth (at opposition) during an orbit of Saturn, 2001–2029"

What is the meaning of "(at opposition)"?

Who someone adds it?

It is impossible to understand that the word opposition refers to similar to in vein with far side of moon.

Semi-protected edit request on 22 May 2024 - Clarification on Saturn rings part

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

Clarification on the creation of the rings. Current part of the rings discussion in this article: "There are two main hypotheses regarding the origin of the rings. One hypothesis is that the rings are remnants of a destroyed moon of Saturn, for which a research team at MIT has proposed the name "Chrysalis"^[1]. The second hypothesis is that the rings are left over from the original nebular material from which Saturn was formed."

Suggested edit: There is a debate on the age of the rings. One side supports that they are ancient, and were created simultaneously with Saturn from the original nebular material (around 4.6 billion years ago)^[2], or shortly after the LHB (around 4.1 to 3.8 billion years ago)^[3]^[4]. The other side supports that they are much younger, created around 100 million years ago^[5]. An MIT research team, supporting the latter theory, proposed that the rings are remnant of a destroyed moon of Saturn, named ″Chrysalis″^[1]. The Space Stout (talk) 11:40, 22 May 2024 (UTC)[reply]

Semi-protected edit request on 8 October 2024

It is requested that an edit be made to the semi-protected article at Saturn. (edit · history · last · links · protection log)

This template must be followed by a complete and specific description of the request, that is, specify what text should be removed and a verbatim copy of the text that should replace it. "Please change X" is not acceptable and will be rejected; the request must be of the form "please change X to Y".

The edit may be made by any autoconfirmed user. Remember to change the |answered=no parameter to "yes" when the request has been accepted, rejected or on hold awaiting user input. This is so that inactive or completed requests don't needlessly fill up the edit requests category. You may also wish to use the {{ESp}} template in the response.

Location: infobox, header: atmosphere.

On page 9 of the given source 26, Saturn's _Surface Pressure_ is estimated at over 1.000 bar (which would be over 100.000 kPa), and it's _Atmospheric Pressure_ is at 140 kPa. Therefor the following suggestion: change surface pressure from "140 kPa" to "over 100.000 kPa", and add a new parameter called "atmospheric pressure" with the value "140 kPa". Current source is ok for both parameters.

Tvos01 (talk) 20:13, 8 October 2024 (UTC)[reply]

I am now wondering what the infobox as it stands actually means, since Saturn has no definite surface. Double sharp (talk) 09:52, 10 October 2024 (UTC)[reply]

Well, it doesn't have a definitive surface for what we can measure. But all planets need to have a core, which is a surface (liquid or semi-liquid in most cases is the assumption here aswell, but it's a surface). This is why the estimated surface pressure is over a thousand kPa by NASA definitions, which I think is fair.

So, does it have a surface? Yes for sure.

Where is that surface? We don't know. Therefor we can't measure the surface pressure (yet)

Angular Diameter

In the quick info box, at the end the angular size of Saturn is indicated in Arc Minutes ('), the correct way would be in Arc Seconds ("). Simply, if Saturn would be up to 20 arc minutes in angular diameter, it would be two thirds the size of the Sun.
