The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.
The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.
The UAAP Cheerdance Competition is an annual one-day event of the University Athletic Association of the Philippines for cheerdancing. However, it does not count in the tabulation to determine the UAAP Overall Championship. The sequence of the performance are determined by drawing of lots prior the competition.
Since 2006, side-court reporters of each participating universities join the main host of the event. Before the announcement of winners and after all squads have performed, a recap is shown during the telecast. Only the Top 3 are announced at the end of the competition. The 2015 UAAP Cheerdance Competition was the most attended UAAP event with a record-breaking 25,388 paying audience.
The competition rules has been revised through the years since it began. The following is based on the most recent rules drafted in 2012.
