Callisto is expected to be captured into the resonance in about 1.5 billion years, completing the 1:2:4:8 chain. [45] Like most other regular planetary moons, Callisto's rotation is locked to be synchronous with its orbit. [4] The length of Callisto's day, simultaneously its orbital period, is about 16.7 Earth days.
Titian's Diana and Callisto (1559) portrays the moment when Callisto's pregnancy is discovered. As a follower of Artemis, Callisto, who Hesiod said [6] was the daughter of Lycaon, king of Arcadia, [7] took a vow to remain a virgin, as did all the nymphs of Artemis. According to Hesiod, [8] she was seduced by Zeus, and of the consequences that ...
It was discovered by Johann Palisa on 8 October 1879, in Pola, and was named after the same nymph Callisto in Greek mythology as Jupiter's moon Callisto. Photometric measurements during 2009 produced a lightcurve that indicated a sidereal rotation period of 19.489 ± 0.002 h with a variation amplitude of 0.18 ± 0.02 magnitudes.

Callisto is surrounded by an extremely thin atmosphere composed of carbon dioxide [49] and probably molecular oxygen. [50] Investigation revealed that Callisto may possibly have a subsurface ocean of liquid water at depths less than 300 kilometres. [51] The likely presence of an ocean within Callisto indicates that it can or could harbour life.

The prehistory of the Philippines covers the events prior to the written history of what is now the Philippines.The current demarcation between this period and the early history of the Philippines is April 21, 900, which is the equivalent on the Proleptic Gregorian calendar for the date indicated on the Laguna Copperplate Inscription—the earliest known surviving written record to come from ...
The history of the Philippines dates from the earliest hominin activity in the archipelago at least by 709,000 years ago. [1] Homo luzonensis, a species of archaic humans, was present on the island of Luzon [2] [3] at least by 134,000 years ago. [4] The earliest known anatomically modern human was from Tabon Caves in Palawan dating about 47,000 ...
