Mercury is the closest to the sun in the solar system. Is it the hottest planet?

Mercury, its temperature is the highest, but why is the temperature of Venus higher than that of Mercury? Although Venus is not as close to the sun as Mercury, Venus is indeed the hottest, which is why.

Although mercury is closest to the sun, it lacks the necessary atmosphere. According to the analysis of astronomers, Mercury's atmosphere is very thin. If compared with Venus' atmosphere, it is basically negligible, which also leads to its inability to store heat in the surrounding space. And because of the lack of atmosphere, the temperature it gets from the sun will be reflected back quickly, but friends can't underestimate Mercury because it can't keep the temperature. Therefore, it also creates its peculiar landscape, that is, with its back to the sun, the temperature can reach 430 degrees Celsius, while the temperature with its back to the sun can reach MINUS 100 degrees, which is really like a hell of ice and fire.
