Object description
| Object type | Planet |
| Visual magnitude | -2,5 |

| Dimension seen from Earth | 44,2 arc seconds |
| Distance Mars - Earth when shooting | 4,454917 AU (666,45 million km) |
| Currently, Jupiter is in opposition to the earth, which means that it is closest to the earth. It is at its minimum opposition. Jupiter is a giant gas planet. It is the largest planet in the solar system, larger and more massive than all the other planets combined, and the fifth planet by its distance from the Sun (after Mercury, Venus, Earth and Mars). Taking into account the average atmospheric agitation (3/5), we can appreciate a very good resolution of the planet. It was not possible to know the transparency of the sky, because the cloud cover was too important. My personal assessment is average transparency (3/5). I was very keen to take the planet that night because it was at its minimum opposition. To better combat the air turbulence, I used the image with the red filter as the luminance image, because the latter is less sensitive to the atmospheric agitation of the Earth. |
