Hace 1 día · Its mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System. Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen , carbon , neon , and iron .
Hace 5 días · Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust known as the interplanetary medium.
Hace 3 días · coronal mass ejection (CME), large eruption of magnetized plasma from the Sun ’s outer atmosphere, or corona, that propagates outward into interplanetary space. The CME is one of the main transient features of the Sun.
Hace 1 día · Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life.
Hace 1 día · At the upper end of the mass range, the supernova is unusually luminous and extremely long-lived due to many solar masses of ejected 56 Ni. For even larger core masses, the core temperature becomes high enough to allow photodisintegration and the core collapses completely into a black hole.
Hace 1 día · In 2020, new observational data from the space-based Solar Mass Ejection Imager aboard the Coriolis satellite and three different modeling techniques produced a refined parallax of 5.95 +0.58 −0.85 mas, a radius of 764 +116 −62 R ☉, and a distance of 168.1 +27.5 −14.4 pc or 548 +90
Hace 6 días · The power of the Sun at the Earth, per square metre is called the solar constant and is approximately 1370 watts per square metre (W/m 2 ). The solar constant actually varies by +/-3% because of the Earth's slightly elliptical orbit around the Sun.
