Planets Home Page

for what a remarkable configuration of a planet is, check our tutorial 'Planets Apparent Motion'

Mercury is reaching a superior conjunction on Sep. 4, by 01:26 UT. It is unobservable worldwide. It's a low evening star by late month at the Tropics and the southern hemisphere, or not seen in the northern hemisphere

Venus, after a superior conjunction last month, is reappearing theoretically like a evening star, about Sep. 15 worldwide

Mercury and Venus may be searched by twilight by late month! picture site 'Amateur Astronomy' based upon the Stellarium software

Mars is reaching a conjunction on Sep. 2, by 10:18 UT. The Red Planet thus is no seen anywhere in the world

Jupiter is now tending low southwest in the northern hemisphere by 10:30 p.m. local time as it is keeping relatively high at the Tropics or the southern hemisphere. Jupiter atop the arch of stars of Scorpius, the Scorpion is also a fine evening star in the northern hemisphere

Saturn is now past South in the northern hemisphere by 10:30 p.m. local time. It's high southwest at the Tropics, or high West in the southern hemisphere. Following a ring aperture maximum, rings now are closing

Uranus Tending to its Best! is closing its year's best with a opposition next month. Uranus is now already risen in the northern hemisphere by 10:30 p.m. local time, tending high at the Tropics, but keeping low in the southern hemisphere

Neptune Faraway World At its Best Now! is now at its year's best on September 10th by 06:18, a opposition. Neptune is high southeast in the northern hemisphere, by 10:30 p.m. local time. It's tending high at the Tropics, or high, northeast in the southern hemisphere

Pluto keeps high, past South in the northern hemisphere, by 10:30 p.m. local time. It's high southwest at the Tropics and high West 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)

Minor Planets, NEOs Home Page

.Minor Planets .Nearest NEOs

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

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 (JPL) site Center for Near Earth Object Studies (CNEOS) (their section "Close Approaches"). Miscellaneous data are available. For further observational purposes, check at their ephemeris Generator (via Tools/Neo DB Query). For more about NEOs see tutorial "About NEOs"

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 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

• Alpha Aurigids back are usually active Aug. 25-Sept. 5-8 with their peak usually on Sep. 1. Their radiant is at R.A. 084° and dec. +42°. Their hourly rate is of 7-10
• Shooting stars afficionados may turn to such dedicated sites like IMO, The International Meteor Organization for more about the above and about possible minor showers this month

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 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

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!

Saturn back is occulted by Moon on Sep. 8th, 2019 by 14:00 UT! The show is available for E. Africa, Madagascar, S. Indonesia, W. and N. Australia, W. Micronesia, W. Melanesia. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)

Pluto back is occulted by Moon on Sep. 9th, 2019 by 03:00 UT! The show is available for Polynesia (except Hawaii), Easter Island, Galapagos Is., N. South America. check more at such sites like "The International Occultation Timing Association" (I.O.T.A.)
