Comet C/2019 K7 (Smith) reaches perihelion.

Comet  C/2019 K7 (Smith) will reach its perihelion (the closest point on its orbit to the Sun) at 6.32 pm GMT on Tuesday 16 June 2020, when it was approximately 4.48 AU from the Sun (i.e. 448% of the distance between the Earth and the Sun, roughly three times as far from the Sun as the planet Mars). At this time the comet will be 3.81 AU from the Earth, in the constellation of Delphinus, having a magnitude of 16.0 (roughly the same as Pluto's moon Charon), making it visible with only the largest Earth-based telescopes, although it may be possible to capture an image of it with a smaller telescope linked to a camera with a sufficiently long exposure.

Comet C/2019 K7 (Smith) imaged on 5 October 2019 using a 60 second exposure of from a 345 mm telescope. The comet is the point at the centre of the image indicated by the two yellow lines. Toshihiko Ikemura/Hirohisa Sato/Seiichi Yoshida.

Comet C/2019 K7 (Smith) was discovered on 30 May 2019 by astronomer Ken Smith using the Atlas MLO Telescope at Mauna Loa Observatory in Hawaii. The designation C/2019 K7 (Smith) implies that the object is a comet (C/), that it was the seventh such object discovered (7) in the second half of May 2019 (period 2019 K) and that it was discovered by Smith.

C/2019 K7 (Smith) is a Parabolic Comet, which is to say a comet that has been disrupted from an orbit in the Oort Cloud, and to be passing through the Inner Solar System on a parabolic orbit that will probably not bring it back again. This parabolic trajectory tilted at an angle of 103° to the plain of the Solar System.
