(2201) Oljato, observing an object from different angles

(2201) Oljato is an apollo asteroid discovered in December of 1947. There is a prediscovery image back to December of 1931. After its discovery, the asteroid was lost until its rediscovery in November of 1979. It received its official name in March of 1983.

Its orbit is located between Mercury-Venus and the Hilda zone.
It has a perihelion of 0.62 AU and an aphelion of 3.72 AU. The semimajor axis is at 2.17 AU. It has an orbital period of 3 years and 76 days. It has an inclination of 2.5º. It has a diameter of about 2 km.

Photometric observations were made in October of 2004.


Orbital resonance:
15:11 with Juno (99.6%)
5:3 with Interamnia (99.9%)
14:9 with Psyche (99.9%)
7:4 with Davida (99.8%)
17:10 with Europa (99.8%)
7:4 with Euphrosyne (99.8%)
4:3 with Eunomia (99.5%)



Geographical place

Oljato-Monument Valley is located in San Juan County in the State of Utah in the United States.

The time of the rediscovery of (2201) Oljato and its official name assignation, clashed with the appearance of the first Japanese animated films and the movie "Tron" (1982), made with computer help to simulate difficult displacements of the filming angle.

(2201) Oljato is related with the observation of objects from different angles to get a clearer idea of their characteristics (5:3 resonance with Interamnia).

(1184) Gaea, commit to the group and vice versa

(1184) Gaea is a main belt asteroid discovered in September of 1926. It was spotted without being identified in July of 1930 and December of 1931.
 

The orbit is located in the middle main belt. It has a perihelion of 2.48 AU and an aphelion of 2.85 AU. The semimajor axis is at 2.66 AU. It has an orbital period of 4 years and 131 days. It has an inclination of 11.3º (quartioctile@11.2, 0º04' orb). It has a diameter of about 12 km. 

Photometric observations were carried out in January and November 2011 and August 2014.


Orbital resonance:
1:1 with Juno (99.9)
5:6 with Vesta (99.9)
5:4 with Europa (%100.0)
9:7 with Euphrosyne (%100.0)

Greek mythology

Gaea was the goddess who personified the Earth, considered as a superorganism, in which every element of it benefits everyone and oneself, by contributing to maintain adequate conditions for life (Gaia hypothesis).

(1184) Gaea is related with the ability to commit to the group, and vice versa (1:1 resonance with Juno and 5:4 with Europe), like in the movies "Unstoppable" (2010) and "Getaway" (2013).
