A planet five times the size of Earth was found to be the shiniest planet outside our solar system. This ultra-hot planet "shouldn't exist" as it is and could be a new class of planet altogether. This planet's hot metal atmosphere is defying astronomers' rules for how planets of this size should behave. Venus, the solar system's shiniest planet, reflects 75% of the sunlight. "We believe these metal clouds help the planet to survive" in these conditions said study author Sergio Hoyer of the Marseille Astrophysics Laboratory.
