Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth ), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation.
The field of planetary astronomy is a subdiscipline of astronomy dealing with observations of the members of our own solar system carded out from ground-based, airborne, and orbiting observatories. It employs many of the same facilities and techniques that are used by other astronomers, spanning the electromagnetic spectrum and encompassing ...
Advancing Knowledge of Other Worlds. For decades, NASA’s planetary science program has advanced scientific understanding of our solar system in extraordinary ways, pushing the limits of spacecraft and robotic engineering design and operation.
Planetary science is the study of planetary processes across the solar system. Planetary scientists come from many different fields, including geology, physics, chemistry, biology, and computer science.
Since the 1990s, astronomers have found thousands of planets, including stars hosting multiple worlds – true planetary systems. Astronomers refer to a planet beyond our solar system as an exoplanet.
2 days ago · solar system, assemblage consisting of the Sun—an average star in the Milky Way Galaxy—and those bodies orbiting around it: 8 (formerly 9) planets with more than 210 known planetary satellites (moons); many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust known as the ...
By the 17th century, astronomers (aided by the invention of the telescope) realized that the Sun was the celestial object around which all the planets – including Earth – orbit, and that the Moon is not a planet, but a satellite of Earth. Uranus was added as a planet in 1781 and Neptune was discovered in 1846.
