I happen to live in a country that is literally wider (5500 km) than the planet Mercury, and also Ganymede and Titan for good measure and pretty close to the diameter of Mars as well. Russia, Canada, China, the US, Brazil, Australia, India, Argentina, Kazakhstan, Algeria, Congo, and Denmark, in that order. Unsurprisingly, things get very different from one place to the next. In Vancouver, it's like the weather of Britain. IE dreary, wet, cool, and cloudy. Where I am in contrast, it genuinely can go from -40 degrees Celsius to +40 degrees Celsius in a few months, can be dark for less than 4 hours on June 21, and has a colder average winter than Moscow in Russia. In the South, you can go from about 15 hours of night or day to the inverse (on the solstices), all the way to where the Sun literally never shines or always shines on the solstice for months and presumably makes Vitamin D supplement companies rich.
