Titan's oblateness may also help explain why its methane lakes are concentrated near the poles. |

The degree of this oblateness is small, the researchers report in a paper published online by Science. |
|
Newton's derivation of the precession from the gravitational action of the Moon and Sun raised three unresolved questions: What are the correct values for the mass of the Moon and the oblateness of the Earth? |
|
Such activity can lead to changes of oblateness and angular momentum and, through gravity coupling, to orbital period modulation. |
|
Oblateness can be considered as a sign of internal cohesive forces within an object and these are absent within a gaseous star. |
