Mercury is reaching a greatest eastern elongation on Jul. 30 by 03:59. Mercury is climbing in the sky like a evening star, West, all month long worldwide. Its best seen -- albeit no that high -- is at the Tropics and the southern hemisphere as the show is low and by late month only in the northern hemisphere

Venus, after a greatest western elongation last month, is still high like a morning star worldwide

Mars is now unobservable worldwide as the Red Planet is reaching its bi-yearly conjunction by July 26th at 23:59

Jupiter is now still high by 10:30 p.m. local time in the northern hemisphere, about the same at the Tropics, and idem in the southern hemisphere. Jupiter is a fine and high evening star in the northern hemisphere

Saturn Still At its Best! keeps at its best after its opposition last month. Saturn is before South in the northern hemisphere, relatively high, much high by that same time, South at the Tropics and about the zenith in the southern hemisphere. A ring maximum aperture is reached in 2017

Uranus is rising by 1:10 a.m. local time in the northern hemisphere, 0:45 a.m. at the Tropics, and 1:10 a.m. in the southern hemisphere

Neptune is now rising by 11:20 p.m. local time in the northern hemisphere, 10:00 p.m. at the Tropics and 9:45 p.m. in the southern hemisphere

Pluto Faraway World At its Best Now! is reaching its year's best by July 10th, 2017, or its opposition. Pluto is now southeast, not that high in the northern hemisphere, much high, at that azimuth at the Tropics and very high, past East, in the southern hemisphere (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)

arrow back Minor Planets

Minor 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

Juno reaches a opposition on July 2nd, 2017, at the 9.8th magnitude . more about Juno in 2017 at our "Minor Planets in 2017"

arrow back Nearest NEOs

Some 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 "About NEOs"

arrow back Comets Home Page

Once 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 . Our 'Comets and Comet Hunting' tutorial will also be helpful. Remarkable comets otherwise usually will be presented below!

->of note: dates of swarms and peaks as given below are the average ones. More refined dates may be given in the Ephemerids section

->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"

arrow back Occultations Home Page

Each 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

Faraway Neptune back, is occulted by Moon on July 13th by 18:00 UT! The show is available for most of Antarctica, New Zealand, and Chatham Island. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)

Aldebaran back, the bright star to constellation Taurus, the Bull is occulted by Moon on July 20th by 00:00 UT! The show is available in India, Central and N.E. Asia, Aleutian Is., and Hawaii. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)

Mercury back is occulted by Moon on July 25th by 09:00 UT! The show is available in N. Europe including British Isles, most of Greenland, and N. half of Asia. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)

Regulus back, the bright star to constellation Leo, the Lion is occulted by Moon on July 25th by 11:00 UT! The show is available in the N. half of Africa, Middle East, S. India, and Indonesia. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)
