It is approx 73 million square kilometres.
Callisto is one of the four largest moons of Jupiter. It is known for its heavily cratered surface and its icy composition. Callisto is considered to be one of the most heavily cratered bodies in the solar system.
No, Callisto hasn't had any internally driven resurfacing within the past 3 billion years. It may have liquid water inside its core, but if it does it hasn't done anything to resurface the moon like we see with Europa.
Jupiter's two largest moons are Ganymede and Callisto. Ganymede is the largest moon in the solar system and is even bigger than the planet Mercury. Callisto is the second largest moon of Jupiter and is known for its heavily cratered surface.
No, Callisto does not have any active volcanoes. Its surface features primarily consist of impact craters, as well as some subtle volcanic features such as calderas and domes that suggest past volcanic activity.
Jupiter's four largest moons are Io, Europa, Ganymede, and Callisto. They are different in terms of their surface features and composition. For example, Io has active volcanoes, Europa has a frozen surface with potential subsurface ocean, Ganymede is the largest moon and has its own magnetic field, and Callisto has a heavily cratered surface.

Callisto is one of Jupiter's moons and it is the most heavily cratered object in the solar system. It has a very thin atmosphere composed mostly of carbon dioxide. Callisto's surface is icy and heavily marked by impact craters of various sizes.
Callisto's surface age is 4 billion years old.

No, there is no evidence to suggest that the moon Callisto has diamonds on its surface. Callisto is primarily composed of water ice and rock, and there is no known geological process that would lead to the formation of diamonds on this moon.
From brightest to dimmest, the order of brightness for the four largest moons of Jupiter when viewed from its surface is Io, Europa, Ganymede, and Callisto. Io tends to be the brightest due to its active volcanism, while Callisto is the dimmest because of its icy composition and lack of surface activity.
Jupiter's moon Callisto has the temperature 134 k (kelvin) or -139 c (Celsius)
The surface of Callisto is heavily cratered and extremely old. It does not show any sign of volcanic activity.
