Astronomical objects discovered in 1968

10988 Feinstein (provisional designation 1968 OL) is a stony Phocaea asteroid from the inner regions of the asteroid belt. Approximately 3.4 kilometers in diameter, it was discovered on 28 July 1968 by astronomers at the Félix Aguilar Observatory in El Leoncito, Argentina. The asteroid was named after Argentine astronomer Alejandro Feinstein in 2008.

1889 Pakhmutova, provisional designation 1968 BE, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 35 kilometers in diameter.

1831 Nicholson, provisional designation 1968 HC, is a stony asteroid of the Baptistina family from the inner regions of the asteroid belt, approximately 8 kilometers (5 miles) in diameter. It was discovered on 17 April 1968, by Swiss astronomer Paul Wild at the Zimmerwald Observatory near Bern, Switzerland. The S-type asteroid has a rotation period of 3.2 hours. It was named for American astronomer Seth B. Nicholson.

1992 Galvarino, provisional designation 1968 OD, is an Eoan asteroid from the outer region of the asteroid belt, approximately 10 kilometers in diameter.

1830 Pogson, provisional designation 1968 HA, is a stony Florian asteroid and an asynchronous binary system from the inner regions of the asteroid belt, approximately 8 kilometers (5 miles) in diameter. It was discovered on 17 April 1968, by Swiss astronomer Paul Wild at the Zimmerwald Observatory near Bern, Switzerland. The S-type asteroid has a rotation period 2.6 of hours. It was named for English astronomer Norman Pogson. The discovery of its 2.5-kilometer sized companion was announced in May 2007.

2028 Janequeo, provisional designation is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter. It was discovered on July 18, 1968, by Chilean astronomers Carlos Torres and S. Cofre at the Cerro El Roble Station of Chile's National Astronomical Observatory. The asteroid named after the indigenous heroine Janequeo (Yanequén).

UGC 11411 is an irregular blue compact dwarf galaxy located 15 million light years from Earth in the constellation of Draco. The first known reference to this galaxy comes from volume IV of the Catalogue of Galaxies and of Clusters of Galaxies compiled by Fritz Zwicky in 1968, where it was listed as CGCG 341-018.

PKS 2134+004 is a distant radio-loud quasar located in the constellation of Aquarius with an approximate magnitude of 18. Its redshift is (z) 1.944 and it is classified as a compact source. It was discovered in a survey by A.J. Shimmins in 1968. This object contains a radio spectrum appearing as flat, making it a flat-spectrum radio source. The spectrum of the source shows an absorption feature.

NRAO 190 is a blazar located in the constellation of Eridanus. Its redshift is (z) 0.844 and it was first discovered as an astronomical radio source via a high-resolution radio interferometry observation in 1968 by astronomers. The radio spectrum of the object is considered as flat, leading to it being classified as a flat-spectrum radio source.

UGC 11861 is a barred spiral galaxy in the constellation of Cepheus. Its velocity with respect to the cosmic microwave background is 1334 ± 10 km/s, which corresponds to a Hubble distance of 19.68 ± 1.39 Mpc (~64.2 million light-years). In addition, three non redshift measurements give a distance of 18.933 ± 5.26 Mpc (~61.7 million light-years). The first known reference to this galaxy comes from volume IV of the Catalogue of Galaxies and of Clusters of Galaxies compiled by Fritz Zwicky in 1968, where it was listed as CGCG 343-003, and described as an "extremely diffuse spiral".
