See that bright, glowing object with a tail? That's not a comet. That's the planet Mercury.

I asked AI... "Standing on Mercury at the hot–cold boundary wouldn’t be survivable, and it wouldn’t feel “moderate” — it would be a chaotic mix of extreme heat, extreme cold, and space hazards. You’d be exposed to vacuum Hit by intense radiation Experience extreme thermal stress"

The reason it has a tail is because micrometeoroids bombard the planet surface and knock tiny pieces of it into space. Those pieces contain mineral-building atoms like sodium—which, when hit by sunlight, glow. So what you're seeing is a thin, glowing trail of pieces of Mercury.

This photo was taken by Dr. Sebastian Voltmer with a filter specially designed to more easily resolve the sodium glow from Mercury. The Pleiades star cluster is above Mercury in this stunning photo.

It's probably losing mass. But at such a slow rate that it doesn't really make much difference to the planet between now and when the Sun is going to vapourise it.

Oh, they do, but Mercury has (for all intents and purposes) no atmosphere, so even tiny things hit into the surface. On Earth, our somewhat thick atmosphere protects us from small and tiny impactors.

Check yourself. Read the thread. The photo is a few years old. I am a professional planetary scientist who worked on the only spacecraft mission to orbit Mercury. It most certainly does have a tail. That's not a meteor. Mate.
