  • New Dwarf Planet Discovery Challenges Planet 9 Speculation

    Discovery of a brand new potential dwarf planet within the outer reaches of the photo voltaic system has posed the best problem but to the speculation {that a} ninth planet lurks removed from the solar. This newly discovered trans-Neptunian object (TNO) named 2017 OF201 has extremely elongated orbit (1,600 occasions that of the Earth’s orbit) that takes it greater than 157 billion miles (244 billion kilometers) from the solar. In keeping with researchers it is vitally uncommon to find an object each massive (estimated diameter of 435 miles) and with an unique orbit.

    The New Dwarf Planet

    In keeping with the pre-print of a paper describing the invention, with an estimated diameter of 435 miles, 2017 OF201 is massive sufficient to be thought-about a dwarf planet.

    Though Planet 9 may enable for such deviations, its gravitational pull would render these orbits unstable over thousands and thousands of years. This mismatch between concept and commentary places Planet 9’s existence underneath scrutiny.
