WOW! Comet Atlas Is Now Visible on STEREO Sat - ESA's Solar Orbiter Set to Pass Through Its Tails
Comet C/2019 Y4 (ATLAS) is now showing up in SECCHI/HI-1 field of view on STEREO-A. It will be visible for the next couple of weeks, including its perihelion on May 31st. The comet is heading for a close encounter with the Sun and it's still alive.
Solar Orbiter to Pass Through the Tails of Comet ATLAS
ESA's Solar Orbiter spacecraft will cross through the tails of Comet ATLAS in the next few days. The mission's 4 in-situ instruments will be switched on and collecting data during the encounter. Solar Orbiter will cross the ion tail of Comet ATLAS on 31 May–1 June, and the dust tail on 6 June.
ESA's spacecraft is currently circling our parent star between the orbits of Venus and Mercury with its first perihelion to take place on 15 June, around 77 million kilometres from the Sun.
