🪐2025 Planetary Season Summary by ©Triton Yung using G3M678M, G3M678C and ATR585C
This image presents the major Solar System bodies captured from 2025 through early 2026, offering a direct comparison of their apparent disk sizes and visible details throughout the observing season.
At the top are the outer planets. Neptune, imaged on September 25, 2025, appears as a small pale-blue disk with a smooth, uniform atmosphere. Below it, Uranus, captured on the same date, shows a slightly larger cyan-blue disk.
On the right is Saturn, also photographed on September 25, 2025. Its pale yellow cloud bands are visible across the globe, while the ring system is sharply resolved, with the contrast between the A and B rings and the clearly defined Cassini Division prominently displayed.
At the center is Jupiter, captured on January 16, 2026. As the largest planet in the Solar System, it dominates the composition. The image reveals complex atmospheric turbulence, alternating cloud belts, and the iconic Great Red Spot in the southern hemisphere. Near the equatorial region, Io and its shadow can be seen transiting the Jovian disk. Also marked nearby is Ceres, photographed on September 25, 2025, appearing as a tiny point of light.
In the lower left is Mars, captured on January 16, 2025, showing its orange-red disk with distinct dark albedo features, including Syrtis Major Planum, along with bright cloud structures near the polar region.
At the extreme lower-left corner is Venus, imaged on January 11, 2025, appearing as a bright crescent phase with a smooth terminator. Its thick cloud cover gives it a uniform gray-white appearance with no visible surface detail.
The images have been proportionally scaled to objectively showcase the planets’ apparent sizes, phase changes, and atmospheric or surface features during the 2025 planetary observing season.
