Details:
Mars and its last opposition.
This fourth planet in order orbits the Sun once every 687 days. while the Earth in 365 days. Thanks to this, the opposition of Mars occurs every 780 days. Opposition is the name for the moment when the planet is directly behind it, or 180° from the Sun, as seen from Earth. The last such opposition occurred on January 16, 2025.
I have been photographing Mars regularly since August of last year, thanks to which this sequence was created showing the change in the phase of Mars (yes, Mars also has partial phases) and at the same time the change in its diameter in the sky.
Now there is a period when, at the time of future oppositions, Mars will be in its orbit near aphelion, or farthest from the Sun and at the same time further from the Earth. For comparison, at the aforementioned time of aphelion, Mars can be up to 101 million kilometers away from Earth at opposition and 55 million kilometers away at perigee.
At the last opposition on January 16, 2025, Mars' distance from Earth was 96.1 million kilometers.
We will have to wait until 2033 and 2035 for close oppositions.
I took the photos through my Newton 150/750 PDS on an EQM35proGoto parallactic mount with an ASI678MC planetary camera + I also used an Explore Scientific 3x barlow.
