Gamma Trianguli Australis represents the State of Parana on the flag of Brazil.

Distance: 8 light-years, Magnitude: 7.4

Lalande 21185 is a type-M red dwarf main sequence star with about 46% solar masses and 3383°K cool, emitting most of its energy as infrared radiation. The proportion of elements other than hydrogen and helium is estimated based on the ratio of iron to hydrogen in the star when compared to the Sun, indicating that the proportion of iron is about 63% of the Sun. Lalande 21185 is also listed as a BY Draconis type variable star in the General Catalogue of Variable Stars, designated NSV 18593.

M25 (Open Cluster) in Sagittarius

Magnitude: 14.5

Cruising along about 2,060 light-years away, M25 spans about 19 light-years across. Caught inside of its influence are four giant stars - two of spectral type M and two of type G. It contains the variable star U Sagittarii, a Delta Cephei-type, which lets us know this group of 86 or so stars may have began life together 90 million years ago.

A small constellation east of Bootes. Its most significant mark is the 2nd-magnitude star Alphecca which lines up with six other stars to form a semicircle. The merged shape renders the constellation relatively hard to find.

Discovered in 1786, comet 2P/Encke is a short-period comet with the shortest known period of 3.3 years and nucleus 4.8 km wide. Encke's orbit is moderately inclined to the ecliptic (12°) in that the comet is often perturbed by the inner planets, rendering its orbit unstable. Encke can get as close as 26 million km to Earth. Such approaches occur about every 33 years. The last perihelion occurred on November 21st 2013. On Nov. 18th 2013, comet Encke passed within 0.025 AU of Mercury, followed a day later by Comet C/2012 S1 (ISON) at 0.24 AU.

Semi-major: 232.39674 AU, Size: 375 km

Discovered on February 6, 2000, up to 375 km wide 2000 CR105 is the forth most distant known TNO from the Sun. The object is a member of the inner Oort Cloud and moves at a maximum distance of 403.3 AU on a moderately inclined (22.8 deg) but strongly elliptical (ecc=0.8) orbit. This orbit takes the object to a perihelion at 44.03 AU from the Sun. Its orbital period is 3,345.87 years. Possibly a dwarf planet, outside the gravitational influence of Neptune, in that its orbit cannot yet be explained.

Nereid (moon of Neptune)

Discovered in 1949, Nereid is unique because it has one of the most eccentric orbits of any moon in our solar system. Nereid is so far from Neptune that it requires 360 Earth days to make one orbit. This odd orbit suggests that Nereid may be a captured asteroid or Kuiper Belt object or that it was greatly disturbed during the capture of Neptune's largest moon Triton. Nereid's spectrum suggests water ice on its surface.
