Stars Lacaille gave 15 stars
Bayer designations Alpha through Pi in 1756, but omitted Iota, Omicron, and Xi, and labelled two stars as Eta and Pi. Mu Doradus was removed from star catalogues because of its dimness.
Alpha Doradus is a blue-white star of magnitude 3.3, 176 light-years from Earth. It is the brightest star in Dorado.
Beta Doradus is a notably bright
Cepheid variable star. It is a yellow-tinged supergiant star that has a minimum magnitude of 4.1 and a maximum magnitude of 3.5. One thousand and forty light-years from Earth, Beta Doradus has a period of 9 days and 20 hours.
R Doradus is one of the many
variable stars in Dorado.
S Dor, 9.721
hypergiant in the
Large Magellanic Cloud, is the prototype of
S Doradus variable stars. The variable star
R Doradus 5.73 has the
largest-known apparent size of any star other than the Sun.
WOH G64 is a binary system in the Large Magellanic Cloud that contains the
largest known star with a well defined radius at 1,540 ± 77 solar radii.
Gamma Doradus is the prototype of the
Gamma Doradus variable stars.
Supernova 1987A was the closest supernova to occur since the invention of the telescope.
SNR 0509-67.5 is the remnant of an unusually energetic Type Ia supernova from about 400 years ago.
HE 0437-5439 is a
hypervelocity star escaping from the
Milky Way/
Magellanic Cloud system. Dorado is also the location of the South
Ecliptic pole, which lies near the fish's head. The pole was called "Polus Doradinalis" by
Philipp von Zesen, aka Caesius. In early 2020, the exoplanet
TOI-700 d was discovered orbiting the star
TOI-700 in Dorado. This is the first
potentially Earth-like exoplanet to be discovered by the
Transiting Exoplanet Survey Satellite.
Deep-sky objects Because Dorado contains part of the
Large Magellanic Cloud, it is rich in deep sky objects. The Large Magellanic Cloud, 25,000 light-years in diameter, is a
satellite galaxy of the Milky Way Galaxy, located at a distance of 179,000 light-years. It has been deformed by its gravitational interactions with the larger Milky Way. In 1987, it became host to
SN 1987A, the first supernova of 1987 and the closest since 1604. This 25,000-light-year-wide galaxy contains over 10,000 million stars. All coordinates given are for Epoch

NGC 2080, also called the "Ghost Head Nebula", is an emission nebula that is 50 light-years wide in the Large Magellanic Cloud. It is named for the two distinct white patches that it possesses, which are regions of recent
star formation. The western portion is colored green from
doubly ionized oxygen, the southern portion is red from
hydrogen alpha emissions, and the center region is colored yellow from both oxygen and hydrogen emissions. The western white patch, A1, has one massive, recently formed star inside. The eastern patch, A2, has several stars hidden in its dust. •
Tarantula Nebula is in the Large Magellanic Cloud, named for its spiderlike shape. It is also designated 30 Doradus, as it is visible to the naked eye as a slightly out-of-focus star. Larger than any nebula in the Milky Way at 1,000 light-years in diameter, it is also brighter, because it is illuminated by the open star cluster
NGC 2070, which has at its center the star cluster
R136. The illuminating stars are
supergiants. •

N44 is a
superbubble in the Large Magellanic Cloud that is 1,000 light-years wide. Its overall structure is shaped by the 40 hot stars towards its center. Within the superbubble of N44 is a smaller bubble catalogued as N44F. It is approximately 35 light-years in diameter and is shaped by an incredibly hot star at its center, which has a
stellar wind speed of 7 million kilometers per hour. N44F also features dust columns with probable
star formation hidden inside. ==Equivalents==
