Roche limit result cannot be represented in an exact algebraic formula. Roche himself derived the following approximate solution for the Roche limit: However, a better approximation that takes into account the primary's oblateness and the satellite's mass is: where formula_59 is the oblateness of the primary. The numerical factor is calculated with the aid of a computer. The fluid solution is appropriate for bodies that are only loosely held together, such as a comet. For instance, comet Shoemaker–Levy 9's decaying orbit around Jupiter passed within its Roche limit in July 1992, causing it to fragment into a number of smaller pieces. On
Patacamaya also contains two astro-cameras an AFU-75, and CCD SBIG ST-5 among other astronomical equipment. This equipment has been extremely useful for students researching such events as the passing of Halley's Comet and the Shoemaker Levy 9 Comet. Apart from the Observatory, Patacamaya has some other smaller sources of income including a weekly Sunday fair. Agriculture in the area consists mainly of potatoes. Patacamaya is also home to the military unit 'Batallon de Tanques I Calama.' Patacamaya Patacamaya or Patak Amaya (Aymara) is a city in Bolivia, situated in the La Paz Department. It is the seat of the Patacamaya Municipality,
