On April 29th behemoth asteroid 1998 OR2 will make closest approach to Earth at a safe distance of approximately 6 million kilometers. Traveling through the cosmos at 31,320 km/h, 1.8 km wide, 4.1 km long 1998 OR2 reigns as largest near Earth asteroid flyby of the year. There’s no chance of planetary impact and sadly no chance of seeing it without a telescope. Fear not, the Virtual Telescope Project hosts free online viewing starting April 28, 2020.https://www.virtualtelescope.eu/webtv/
