A nice place to start would be the Dao-Dao Islands some seven to ten minutes away from the seaport, when riding a motorboat.It is a rather big island, with an area size of about 1.1057 hectares.
Comparison with stars having similar motion through space gives an age in the range 30–160 million years.
Given the star's position on the Hertzsprung–Russell diagram of luminosity versus temperature, it has an estimated age in the range of 30–1,128 million years.
The best accepted value for an age of HR 8799 is 30 million years, consistent with being a member of the Columba Association co-moving group of stars.
Detailed analysis of the star's spectrum reveals that it has a slight overabundance of carbon and oxygen compared to the Sun (by approximately 30% and 10% respectively).
However, this is disputed because it would make the planets become brown dwarfs to fit into the cooling models.
Brown dwarfs would not be stable in such a configuration.
There is also the White Beach that, as its name suggests, is a stretch of white sand beach just minutes southeast of the seaport. The clear, deep, blue waters (even during low tides) are excellent for swimming and diving.
The Bomba Beach, located in barangay Bomba some 2 kilometers away from the city, is also a good area for swimming and fishing, with a bomba bridge and natural coral reefs.
Finally, Poloyagan Beach have rocky outcroppings and coral reefs so one should be careful in trekking them.
