Ceres: The Hidden Dwarf Planet In The Inner Solar System

Welcome to Ceres—the only dwarf planet residing among the inner planets. In this video, we take a deep dive into the mysterious world of Ceres, orbiting comfortably in the main asteroid belt between Mars and Jupiter in the inner solar system. Learn about its unique characteristics, from its leisurely 4.6 Earth-year orbit and dramatic temperature range to its water-rich composition, where 15% or more of this world may be water, potentially holding more water than planet Earth. We explore its nearly spherical shape, surface features, its low gravity that makes you feel almost weightless, as well as the intriguing bright spots of Occator Crater that hint at ancient cryovolcanic activity and more.

Drawing on up-to-date data and insights from missions like NASA’s Dawn, this video unpacks the science and history behind Ceres—discovered on January 1, 1801 by Giuseppe Piazzi, later reclassified as a dwarf planet in 2006, and still captivating researchers worldwide. Whether you’re an astronomy buff, space enthusiast, or simply curious about our cosmic neighborhood, join me on this journey to understand how Ceres expands our view of the solar system and reminds us of Earth’s unique stability.

How can 15%-25% water of a dwarf planet have more water than earths 70%? This is an impossibility.

He's right there would be less water on this planet
