It is close to the sun and lacks a protective atmosphere
Mercury's extreme temperatures are due to its lack of atmosphere, which makes it difficult for the planet to retain heat. The side facing the sun can reach up to 800 degrees Fahrenheit, while the dark side can drop to -290 degrees Fahrenheit due to the lack of a protective atmosphere to regulate the temperature.
It is not.Until quite recently, it was thought that Mercury was synchronously tidally locked with the Sun, rotating once per orbit so that one side of the planet faced the sun all the time (in the same way that we see one side of the moon). However, radar observations proved, in 1965, that this was not the case: Mercury rotated about its axis 3 times for every 2 revolutions.
Mercury is the smallest planet, so there isn't one with half the diameter.
Mercury although it is almost always half melted, is a terrestrial planet.
No. The gravity on Mercury is less than half that of Earth.

It does not appear to, so far as we can tell at the present time. It would be surprising if it did, considering its proximity to the sun. Half of Mercury is very hot, while the side opposite the sun is extremely cold. Mercury sports an enormous polar impact crater, which could have been an icy comet. If so, it probably largely vaporized on impact.

one half is too hot and the other half is too cold
Mercury is the smallest planet, so there isn't one with half the diameter.
Uranus's moons are made up of half ice (with some ammonia and carbon dioxide) and half rock. Being so far away from the sun, it is extremely cold as well.
Pluto is about half the size of Mercury, which is the smallest "true" planet.
Half of Mercury is icy cold at any time, since it has no atmosphere to distribute the heat received on the solar side. Near the poles, there are craters, the basins of which miss the sunshine all the time. There may be ice there.
The average temperature on earth was 14 or 15 °C (57-59 °F), much hotter on Venus and half of Mercury and much colder on the other half of Mercury, Mars, and the outer planets.
It is the most cratered planet in the Solar System. It has an extremely thin atmosphere. It is named after the Roman delivery god, Mercurius, since it moves quickly along the sky. You can't see it through a telescope since it's too close to the Sun. Mercury has no moons. Since Pluto isn't a planet anymore, Mercury is the smallest planet in the Solar System. It looks almost exactly like the moon and has an Earth like interior.
Mercury although it is almost always half melted, is a terrestrial planet.
