A “lava planet” is a type of exoplanet that is characterized by having a surface that is largely or entirely molten. These planets are typically in very close proximity to their host star, resulting in extremely high surface temperatures that are sufficient to melt rock.

The exact appearance of a lava planet would depend on various factors, including its composition, distance from its star, and atmospheric conditions. However, given that such a planet’s surface is primarily composed of molten rock, we can make some educated guesses. The surface would likely be a glowing, roiling sea of lava, similar to what we see in active volcanic regions on Earth, but on a global scale. The color of the lava could range from bright red to dark gray, depending on its temperature and composition.

It’s important to note that while we can speculate on the appearance of a lava planet, our understanding is based on current scientific knowledge and computer models. As of my last training data in September 2021, no spacecraft had yet visited a lava planet, and no detailed images of such planets had been captured. The discovery and study of exoplanets is a rapidly advancing field, so new information could emerge that alters our understanding of these fascinating celestial bodies.
