About this Episode
On March 30th in the world of astronomy, one of the most notable events occurred in 2014. On this day, astronomers announced the discovery of 2012 VP113, affectionately nicknamed "Biden" after then-Vice President Joe Biden. This dwarf planet candidate is one of the most distant known objects in our solar system, residing in the outer reaches beyond Pluto.
2012 VP113 is part of a region called the Oort cloud, a hypothesized shell of icy objects that exists in the outermost reaches of the solar system. Its discovery was significant because it provided evidence for the existence of a yet-unseen "Super Earth" planet in the outer solar system, which could be shepherding these distant objects into similar orbits.
The dwarf planet candidate is estimated to be about 450 kilometers (280 miles) in diameter and has a pinkish hue, likely due to the effects of cosmic radiation on its icy surface over billions of years. Its orbit takes it as far as 452 astronomical units (AU) from the Sun – that's 452 times the distance between Earth and the Sun!
The discovery of 2012 VP113 sparked excitement in the astronomical community, as it opened up new possibilities for understanding the formation and evolution of our solar system. It also reignited the debate about what constitutes a planet, a topic that had been hotly contested since Pluto's demotion to dwarf planet status in 2006.
So, as you go about your day on March 30, 2025, take a moment to look up at the sky and imagine the tiny, pink "Biden" slowly making its way through the vastness of space, perhaps waving a miniature American flag as it goes. Who knows what other celestial secrets are waiting to be uncovered in the depths of our cosmic neighborhood?
