Planets Home Pagefor what a remarkable configuration of a planet is, check our tutorial 'Planets Apparent Motion'
Mercury is reaching a greatest eastern elongation on June 23, by 22:59 UT. Mercury in June is a fine evening star in the northern hemisphere as the swift planet will keep climbing in twilight until next month. The show is relatively high at the Tropics and the southern hemisphere only

Venus is no more observable worldwide in June as about the horizon. It's barely seen above the horizon in the southern hemisphere only
 | Venus barely above the horizon like a morning star, in the southern hemisphere! picture site 'Amateur Astronomy' based upon the Stellarium software |
Mars is now low in the northern hemisphere, between West and northwest when the twilight settles. It keeps relatively high there at the Tropics, and somewhat lower, about northwest in the southern hemisphere
Jupiter At its Best Now! is at its year's best now as reaching its opposition on June 10th by 15:11! Observe Jupiter! Jupiter in the northern hemisphere, is about southeast, high southeast at the Tropics, and shouldering the zenith in the southern hemisphere. check more about any remarkable position of a planet with our tutorial 'Planets Apparent Motion'
 | Jupiter's best! Observe Jupiter! picture site 'Amateur Astronomy' based upon the Celestia software |
Saturn Tending to its Best! is now tending to its year's best as the ringed planet will reach a opposition next month. Saturn is now rising by 10:30 p.m. local time in the northern hemisphere, as it is already high between East and southeast by that time, at the Tropics. Saturn is also already high in the southern hemisphere by 10:30 p.m. Following a ring aperture maximum, rings now are closing. check more about any remarkable position of a planet with our tutorial 'Planets Apparent Motion'

Uranus is now rising by 3:35 a.m. local time in the northern hemisphere, 3:15 a.m. at the Tropics, and 3:40 a.m. in the southern hemisphere. Uranus keeps unobservable in the northern hemisphere as it is at the Tropics and the southern hemisphere
Neptune is now rising by 1:40 a.m. local time in the northern hemisphere, 0:15 a.m. at the Tropics, and 0:10 a.m. in the southern hemisphere. Neptune is observable worldwide
Pluto will reach a opposition next month. Pluto is now rising as soon as by 10:45 p.m. local time in the northern hemisphere, as it is already high between East and southeast by that time, at the Tropics. Pluto is also already high in the southern hemisphere by 10:30 p.m. (according to the International Astronomical Union (IAU) since 2006, Pluto is not considered a planet anymore, but categorized like a dwarf planet instead along with Ceres, Eris, Makemake, and Haumea, and the prototype of a new category of 'trans-Neptunian', 'Pluto-class' objects)
Minor Planets, NEOs Home Page
Minor PlanetsMinor planets are those biggest asteroids in the Asteroid Belt which may be easily observed by amateurs from the Earth, namely Ceres, Pallas, Juno, and Vesta (due to the new categorization by the International Astronomical Union (IAU) by 2006, Ceres belongs to the 5 dwarf planets in the solar system with Pluto, Eris, Makemake, and Haumea). check data and charts at our section Minor Planets on the yearly Calendar page as our tutorial 'Asteroids and Asteroid Hunting' is of help too. Any remarkable event linked to a minor planet may have a notice here below
Nearest NEOsSome small asteroids dubbed Near-Earth Objects (NEOs) are regularly making close approaches at Earth. People interested in such close approaches may obtain recent and upcoming data at NASA site Near-Earth Object Program (their section "Close Approaches"). Date, miss distance in AU or Lunar Distance (LD), estimated diameter, and relative velocity are available. For further observational purposes, check at the Near-Earth Object Program ephemeris Generator. For more about NEOs see tutorial "
Comets Home PageOnce every time, the solar system treats us with a remarkable comet, a eery view spanning up to thirty degrees of sky! Most of the time however comets are the domain of dedicated observers as mostly weak and, at the most, hovering at the limit of the naked-eye visibility. A good site to get information about current such comets is the British Astronomical Association Comet Section page or also the Weekly Information about Bright Comets page (which often points to comets close to the visual magnitude). Our 'Comets and Comet Hunting' tutorial will also be helpful. Remarkable comets otherwise usually will be presented below!
Shooting Stars Home Page->note: shooting stars afficionados will be aware of checking Moon at the dates of the showers
for more about the meteor showers of this month, for possible other meteor showers for this month, and for more about shooting stars, generally, see our tutorial "Shooting Stars"
Occultations Home PageEach month, Moon occults some relatively bright stars, that is the Moon, beginning either with its bright or its dark visible face, is passing in front of a star. This is called an occultation. The Pleiades, on the other hand, due to their position near the eclipic, are often occulted by Moon too. Some planets, at last, along the year, may be occulted by Moon or they themselves, or their satellites, may be seen too occulting a star. The asteroids too may occult stars. Yearly lists of such phenomenons are to be found at Sky & Telescope/SkyTonight.com, either in their newsstand issues or at their site, as a list of occultations of most brilliant stars, the planets and the Pleiades are available at the I.O.T.A site (I.O.T.A. stands for "The International Occultation Timing Association"). Most notable occultations are signaled below
The configuration of Moon makes 2019 a great year of occultations of planets and minor planets by the Moon as, amazingly none of the bright stars usually occulted by Moon, like Aldebaran, Antares, Regulus or Spica, will be!
Minor planet Ceres back is occulted by Moon on Jun. 15th, 2018 by 15:00 UT! The show is available for Central and E. Russia, N.E. Kazakhstan, N. and E. China, and Japan. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)
Saturn back is occulted by Moon on Jun. 19th, 2018 by 04:00 UT! The show is available for Easter Island, S. South America, Antarctic Peninsula, and southern Africa. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)
Pluto back is occulted by Moon on Jun. 19th, 2018 by 11:00 UT! The show is available for Melanesia, N.E. Australia, S. Micronesia, S. Polynesia, Central America, W. South America. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)
