NASA-Funded Study Examines Tidal Effects on Planet and Moon
15 hours ago· NASA-supported scientists have developed a new method to compute how tides affect the interiors of planets and moons. Importantly, the new study looks at the effects of body tides on objects that don''t have a perfectly spherical interior structure, which is an assumption of most previous models.
Pluto
Pluto is a dwarf planet located in a distant region of our solar system beyond Neptune known as the Kuiper Belt. Pluto was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006. NASA''s New Horizons was the first spacecraft to explore Pluto up close, flying by in 2015. Pluto was discovered in 1930 by astronomer Clyde
NASA''s Webb Confirms Its First Exoplanet
Researchers confirmed an exoplanet, a planet that orbits another star, using NASA''s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth''s diameter. The research team is led by Kevin Stevenson and Jacob Lustig-Yaeger, both of the

Planets Beware: NASA Unburies Danger Zones of Star Cluster
Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets.. A team of astronomers used NASA''s Chandra X-ray Observatory, in combination
Saturn
Saturn is the sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. Saturn is a massive ball made mostly of hydrogen and helium. The farthest planet from Earth discovered by the unaided human eye, Saturn has been known since ancient times.
Jupiter
More recently, this planet has been studied by orbiters, probes, and spacecraft passing by on their way to other worlds. NASA''s Juno spacecraft currently is studying the giant planet from orbit. Europa Clipper launched on Oct. 14, 2024, to study Jupiter''s icy moon, Europa. Learn More About Jupiter Missions

Planets
Planets. In 2006, subsequent to several discoveries of several large outer Solar System objects beyond Pluto (one of which was found to be even larger than Pluto) it was decided that a planet should be defined as an object which (a) orbits the sun, and (b) is massive enough not only to coalesce itself into a nearly spherical shape, but also to gravitationally dominate its region of

What Is a Planet? | NASA Space Place – NASA Science for Kids
A planet must do three things: it must orbit a star, it must be big enough to have enough gravity to force a spherical shape, and it must be big enough that its gravity cleared away any objects of a similar size near its orbit. This cosmic cloud, called Sharpless 2-106, is an area where stars (and planets) form. Credit: NASA/ESA/Hubble
Our Solar System
Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.
Solar System Sizes
This illustration shows the approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, followed by the dwarf planet Pluto. Jupiter''s diameter is about 11 times that of the Earth''s and the Sun''s diameter is about 10 times Jupiter''s.
