Jose A. "Jett" Aguilar (born 1961) is a Filipino neurosurgeon who has saved over 1,000 children in the Philippines by volunteering his time and surgical expertise to treat their congenital malformations and brain tumors. He is also an amateur astronomer and serves as vice president of the Astronomical League of the Philippines [11] · 7431
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Vesta (radius 262.7 ± 0.1 km), the second-largest asteroid, appears to have a differentiated interior and therefore likely was once a dwarf planet, but it is no longer very round today. [74] Pallas (radius 255.5 ± 2 km ), the third-largest asteroid, appears never to have completed differentiation and likewise has an irregular shape.
The first Philippine satellite launched to space was Agila-2 which was placed to orbit in 1997. The Philippine Space Agency is the lead government organization of the Philippine space program since 2019 but all active satellites are built and operated by the Department of Science and Technology (DOST) and its child agencies.
Diwata-1 [6] also known as PHL-Microsat-1 was a Philippine microsatellite launched to the International Space Station (ISS) on March 23, 2016, and was deployed into orbit from the ISS on April 27, 2016. It was the first Philippine microsatellite and the first satellite built and designed by Filipinos. [7] [8] It was followed by Diwata-2 ...
The appearance of the comet in 1759, now named after him, within a month of predictions based on Newton's gravity greatly improved scientific opinion of the theory. [106] Newton's theory enjoyed its greatest success when it was used to predict the existence of Neptune based on motions of Uranus that could not be accounted by the actions of the ...
As the large bodies moved through the crowd of smaller objects, the smaller objects, attracted by the larger planets' gravity, formed a region of higher density, a "gravitational wake", in the larger objects' path. As they did so, the increased gravity of the wake slowed the larger objects down into more regular orbits. [55]
The present name of the Philippines was bestowed by the Spanish explorer Ruy López de Villalobos [1] [2] or one of his captains Bernardo de la Torre [3] [4] in 1543, during an expedition intended to establish greater Spanish control at the western end of the division of the world established between Spain and Portugal by the treaties of Tordesillas and Zaragoza.
