Parker At Perihelion. The
#ParkerSolarProbe is at perihelion, 0.1296 AU. No manmade object has ever been this close to the Sun. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1540859289925_parkerDistances.html …pic.twitter.com/AgIJ8iFwSU

Galileo could have been credited with the discovery of Neptune. He saw it
#OTD in 1613 while Neptune was undergoing retrograde motion around Jupiter. But he mistook it as a background star. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1548523920997_galileoJupiter.html …pic.twitter.com/xnJ5qZaXZA -
Today,
#ParkerSolarProbe breaks its previous record of 0.166 AU for closest distance to the Sun by any spacecraft. Future Venus flybys will send it even closer. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1540859289925_parkerDistances.html …pic.twitter.com/ZuP8SMLTLV -

You can use my program Orbit Simulator. Just type the name of the asteroid into the Import box. Choose a color (optional) and press Import. It retrieves its orbital data from JPL Horizons. Press Play and watch it pass Earth. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1579987302068_gsimNEA.html …pic.twitter.com/6zVyfAwXTU

Newly-discovered
#asteroid 2020 BH6 just passed 0.2 Lunar Distances from Earth. It's slow speed allowed Earth's gravity to bend its path. The orbit of the Moon and and a few geostationary satellites are included for reference. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1579985390525_2020%20BH6.html …pic.twitter.com/IEct7ogZYU -
The
#ParkerSolarProbe is currently crossing the orbit of Mercury. It holds the record for closest spacecraft to the Sun. On Jan 26, it will break its old record of 0.16 AU. On Jan 29, it will set a new record of 0.13 AU. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1540859289925_parkerDistances.html …pic.twitter.com/7t9vVHvlzz

Will is asteroid 165347 Philplait?
@BadAstronomer's asteroid is too dim to see in a backyard telescope. But locating it tomorrow night will be easy. It will be occulted by the rising Moon for much of the U.S. This is a view of Earth from the asteroid. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1578940230785_philplait.html …pic.twitter.com/g3dGxJ8lTZ

In a few hours, you will be closer to the Sun than you've ever been, and ever will be.. Earth reaches
#perihelion. At 23:49 PST, it will be only 147,091,143 km from the Sun (center-to-center). It will not come closer this millennium. http://orbitsimulator.com/gravitySimulatorCloud/simulations/1578186882157_peri2020.html …pic.twitter.com/i46Bi1CJva
