That’s a good question. The reason why stars twinkle but planets don’t is because of the Earth’s atmosphere. The atmosphere is made of different layers of air that have different temperatures and densities. When the light from a star passes through these layers, it bends or refracts slightly. This makes the star appear to change its position and brightness rapidly. This effect is called scintillation or twinkling12.
Planets, on the other hand, are much closer to us than stars. They appear as tiny disks in the sky, not as points of light. When the light from a planet passes through the atmosphere, it also refracts, but the refraction is averaged out over the disk. This means that the planet’s light is more steady and does not twinkle as much12.
The amount of twinkling also depends on how high the star or planet is in the sky. The higher it is, the less atmosphere it has to pass through, and the less it twinkles. The lower it is, the more atmosphere it has to pass through, and the more it twinkles13. That’s why stars near the horizon twinkle more than stars overhead.
When I had that equipment and vehicles.. one time I wanted to try and get sirius out in the country, with it coming up the horizon.. but it's a bit of a bitch out here cause I think it gets into winter, eh. lol. Then ya gotta get out of the city. Where there's no shit on the horizon. Thought it could be like the moon where it's bigger on the horizon but I couldn't get it goin. lol.
It's also good to go and film shit yourself, then you know it's not fucked with by whoever, right.
Let's look around for somebody who filmed sirius on the horizon.
