June's night sky is filled with stars, planets and the moon converging and dancing around the sky for all to see. As the sun sets in the west, the planet Mars can be seen in the constellation Cancer. During June, the planet will be moving eastward (retrograde motion) in relation to the background stars. Over the course of this month, Mars will move closer to the planet Saturn, which resides in the constellation Leo.

The new moon today is the closest new moon of this year.
The moon at perigee will be only 357,253 kilometres from the Earth.
The moon is new every month, when the Sun, Moon and Earth all line up. This can increase the gravitational influence on the oceans, creating higher than usual tides.

High overhead in the early evening a Colorado sky in June is a region of the heavens bounded by the constellations of Leo, Virgo and Coma Bernices, which astronomers have nicknamed "the Realm of the Galaxies."
The planets Mars and Saturn can be seen to the west until about an hour or so before midnight during the month of June. The Red Planet is situated in eastern Cancer to the west of the golden hued Saturn and the bluish Leo star Regulus. As June progresses, the Mars, Saturn, Regulus trio progressively will become more compact heading toward a most striking grouping in early July.

June has only one major meteor shower, the Arietids.
Unfortunatly it is during the daylight hours.
The Earth will pass through a stream of dusty debris. Thought no one is sure where the dust comes from, although some suspect its debris from the sungrazing asteroid 1566 Icarus. Most Arietid meteors are invisible because the Sun is up when the shower is most intense.

Shower Activity Period Maximum Radiant Velocity ZHR
Date R.A. Dec. km/s
June Scutids 3rd June
May-Librids 4th June 16.5h -22.8 12.2 4.2
June Lyrdis June 1-21 5th June 17.3h 40.0 37.2 7
Arietids 12h (daylight) June 2 - 14 8th June 20.9h 57.8 12.4 52.7
Pi Puppids 16th June 7.5h -15.0 24.8 25
Northern May Ophiuchids 17th June 17th June 18.5h 4.3 10
Beta Taurids (daylight) June 6-July 18 May 13-18 79.4 21.2
