we all love Jupiter.

From Wikipedia:

To the Babylonians, this object represented their god Marduk.
They used the roughly 12-year orbit of this planet along the ecliptic to define the constellations of their zodiac.
The Romans named it after Jupiter (Latin: Iuppiter, Iūpiter) (also called Jove),
the principal god of Roman mythology, whose name comes from the Proto-Indo-European vocative compound *Dyēu-pəter (nominative: *Dyēus-pətēr, meaning "O Father Sky-God", or "O Father Day-God").
The astronomical symbol for the planet,
is a stylized representation of the god's lightning bolt.
The original Greek deity, Zeus, adopted by Romans, supplies the root zeno-,
used to form some Jupiter-related words, such as zenographic.
Jovian is the adjectival form of Jupiter.
The older adjectival form jovial, employed by astrologers in the Middle Ages,
has come to mean "happy" or "merry," moods ascribed to Jupiter's astrological influence.
The Chinese, Korean and Japanese referred to the planet as the wood star, Chinese: 木星;
pinyin: mùxīng, based on the Chinese Five Elements.
The Greeks called it Φαέθων, Phaethon, "blazing."
In Vedic Astrology, Hindu astrologers named the planet after Brihaspati,
the religious teacher of the gods,
and often called it "Guru", which literally means the "Heavy One."
In the English language, Thursday is derived from "Thor's day",
with Thor associated with the planet Jupiter in Germanic mythology.
In the Central Asian-Turkic myths, Jupiter called as a "Erendiz/Erentüz",
which means "eren(?)+yultuz(star)".
There are many theories about meaning of "eren".
Also, these peoples calculated the orbit of Jupiter as 11 years and 300 days. They believed that some social and natural events connected to Erentüz's movements on the sky.
