Hace 17 horas · 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 2 días · The mass of the Sun, M ☉, is 743 times the total mass of all the planets in the solar system and 330,000 times that of Earth. All the interesting planetary and interplanetary gravitational phenomena are negligible effects in comparison to the force exerted by the Sun.
Hace 4 días · 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 · It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres (1,516.0 mi). Mercury is also smaller—albeit more massive—than the largest natural satellites in the Solar System, Ganymede and Titan. Mercury consists of approximately 70% metallic and 30% silicate material. Internal structure
Hace 1 día · Dark areas on the sun’s surface called sunspots are also a result of the magnetic field and are thought to be tied to solar flares, coronal mass ejections and other space weather.
Hace 3 días · Jupiter, the most massive planet in the solar system and the fifth in distance from the Sun. It is one of the brightest objects in the night sky; only the Moon, Venus, and sometimes Mars are more brilliant. Jupiter takes nearly 12 Earth years to orbit the Sun, and it rotates once about every 10 hours.
Hace 3 días · An international team of researchers including Northwestern Engineering’s Daniel Lecoanet is getting closer to solving a 400-year-old solar mystery that stumped even famed astronomer Galileo Galilei. Since first observing the sun’s magnetic activity, astronomers have struggled to pinpoint where the process originates.
