The very strange year of 2020: The solar system gets more visitations from a series of comets

The new movie Greenland tells the horrifying story of a rogue comet that is on a near-collision course with Earth

Any given comet entering the inner solar system stands a 40% chance at having its orbit modified by Jupiter on its outbound leg. This famously happened to Comet Hale-Bopp in the late 1990s, and this is also now the case with the 2020 tale of Comet U6 Lemmon.  Up north, we should get our first good views of Comet U6 Lemmon in late June, as the comet vaults up to about 30 degrees above the western horizon at sunset. We’ll see the comet on its outbound leg in July through August, passing through the constellation of Sextans the Sextant, then vaulting northward above the ecliptic into Leo and Virgo. At its brightest, Comet U6 Lemmon may flirt with naked eye visibility in early July, topping out at +5th magnitude. As of writing this in late June, the comet seems to have been an over-performer for southern hemisphere observers, holding at +8 magnitude in early June and approaching +6th magnitude as it neared perihelion.

Moving at its fastest across the sky in late June, the comet will be clear 2 degrees a day, four times the diameter of a Full Moon. The comet just came off of perihelion at 0.915 AU (85 million miles/137 million kilometers) from the Sun on June 18th, and is very slowly revealing itself for northern hemisphere observers low in the dusk sky.   –Universe Today
