The Planets - June 2019

Observing the planets can be extremely rewarding. Everyone remembers the first time they observed Saturn and it's rings or the gas giant Jupiter and it's Galillean Moons. Solar System


Mercury, the innermost planet is now visible low in the north west after sunset. As it moves towards greatest elongation east on June 23rd it rises higher in the sky after sunset.


Venus with a magnitude of -3.8 rises just one hour before the Sun this month whilst its angular size reduces from 10.5 to 9.9 arc seconds as it moves away from the Earth.


Mars can be viewed in the south western sky after sunset. Initially in Gemini, it moves into Cancer on the 28th of the month. Mars sets approx two hours after the Sun at the start of June less than one hour by month's end.


Jupiter reaches opposition on June 10th and is thus visible throughout the night. Jupiter lies in the southernmost part of Ophiuchus up and to the left of Antares in Scorpius.


Saturn now in Sagittarius and lying on the southern side of the milky way. It is at the lowest point of the ecliptic and will only reach an elevation of 14 degrees. As with Jupiter an atmospheric dispersion corrector will help improve observing.
