Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.

The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system’s mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called volatiles, such as water, ammonia and methane. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic. — Wikipedia

  • Field geology at Mars' equator points to ancient...
    on November 20, 2020 at 4:38 pm

    Floods of unimaginable magnitude once washed through Gale Crater on Mars' equator around 4 billion years ago -- a finding that hints at the possibility that life may have existed there, according to data collected by NASA's Curiosity rover.

  • Ancient zircon minerals from Mars reveal the...
    on November 17, 2020 at 4:30 pm

    Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of these zircons, researchers have shown that a population of these crystals were sourced from the deep interior of Mars. If the researchers are correct, it means that the young zircons contain information about the deep, inaccessible interior of Mars, which provides insights into the internal structure of the planet.

  • Scientists expand space instrument's capabilities
    on November 16, 2020 at 4:28 pm

    Scientists have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX now uses two different dating approaches based on rubidium-strontium and lead-lead geochronology methods. The instrument uses laser ablation resonance ionization mass spectrometry (LARIMS) to obtain dates using these methods.

  • Escape from Mars: How water fled the red planet
    on November 12, 2020 at 7:40 pm

    Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. Researchers have discovered a surprisingly large amount of water in the upper atmosphere of Mars, where it is rapidly destroyed, explaining part of this Martian mystery.

    on November 10, 2020 at 4:25 pm

    The first mining experiments conducted in space could pave the way for new technologies to help humans explore and establish settlements on distant worlds, a study suggests.

    on November 9, 2020 at 4:02 pm

    Life is deeply dependent on water, but where does water come from? Based on new research, researchers believe it may emerge in connection with the formation of planets.

    on November 5, 2020 at 6:45 pm

    Diverse microbes discovered in the clay-rich, shallow soil layers in Chile's dry Atacama Desert suggest that similar deposits below the Martian surface may contain microorganisms, which could be easily found by future rover missions or landing craft.

    on November 2, 2020 at 7:22 pm

    The mineral olivine, thought to be a major component inside all planetary bodies, holds secrets about the early formation of the solar system, and a team of researchers has a new way to study it remotely.

  • Water on ancient Mars
    on October 30, 2020 at 6:21 pm

    A meteorite that originated on Mars billions of years ago reveals details of ancient impact events on the red planet. Certain minerals from the Martian crust in the meteorite are oxidized, suggesting the presence of water during the impact that created the meteorite. The finding helps to fill some gaps in knowledge about the role of water in planet formation.
