There's Apparently an Asteroid Between Mercury and Venus - Space News

The video discusses the discovery of asteroid 2020 Av 2, which has the tightest orbit of any known asteroid, and the challenges of observing such asteroids due to their proximity to the sun. It introduces the VATIRA class of asteroids, which orbit closer to the sun than Venus. The video also explores the evolution of Earth's magnetic field, highlighting a study that used zircon crystals to reveal that Earth's early magnetic field was stronger than previously thought. This research provides insights into the planet's geological history and the development of its protective magnetic field.
