EU: 24 biggest craters on Phoebe were named




The other day, the International Astronomical Union officially adopted the new name space objects. This is the name of 24 of the largest craters left by impacts of asteroids on the surface of Phoebe. Phoebe — is one of the distant satellites of Saturn, its diameter is about 220 km. It was discovered by the American astronomer U.Pikeringom in 1898, Phoebe moves around Saturn in a retrograde orbit, that is opposite to the direction of rotation of Saturn around its own axis. The radius of the orbit is about 12,950,000 miles, a complete turn around Saturn's Phoebe makes for 550.4 days.

Astronomers believe that Phoebe was formed more than 4 billion years ago, at the periphery of the solar system, and then it was captured by Saturn's gravitational field.

In June 2004, Cassini flew a distance of 2068 km from the surface of Phoebe and carried out a detailed survey of the satellite. Based on these images, scientists have concluded that Phoebe consists mainly of ice, and its surface is covered with a layer of some dark material thickness of 300-500 sq. These photographs also show that the surface of Phoebe literally riddled with many craters. Twenty four largest craters have decided to assign their own names.

The satellite itself was named in honor of Phoebe — grandmother of Apollo in Greek mythology. However, the legend of Phoebe was quite short and it does not have enough characters to have their names called 24 of the crater. So we decided to take the story of the Argonauts (who, like the probe Cassini, set off to explore unknown lands) and dial from there. Some of these craters with signed names are shown in the pictures shown here.
