    Asteroid 2017 DG16 to flyby Earth at 0.34 LD
    https://watchers.news/2017/02/23/asteroid-2017-dg16-flyby/

    A newly discovered asteroid named 2017 DG16 will flyby Earth at a very close distance of 0.34 LD (130 560 km / 81 126 miles) from the surface of our
    planet at 21:08 UTC on February 23, 2017. This is the fifth known near-Earth asteroid to flyby Earth within 1 lunar distance since January 8, 2017.

    2017 DG16 was first observed by Mt. Lemmon Survey on February 21. The estimated size of this asteroid is between 2 and 8 m (6.5 - 26.2 feet).
    It will flyby Earth at a speed (relative to the Earth) of 6.91 km/s. This object belongs to the Apollo group of asteroids, Earth-crossing asteroids that
    have an orbital semi-major axis greater than that of the Earth (mt 1 AU) but perihelion distances less than the Earth's aphelion distance (q lt 1.017 AU).

    k exoplanetám jsem narazil na zajímavou aplikaci, shrnující dosavadní poznatky. jestli už to tu v minulosti proběhlo, může se hodit k připomenutí. (nechť to admin klidně smaže, bylo-li to nedávno)

    The K2 mission, the spacecraft's second gig, is observing TRAPPIST 1 now! What else might we learn? Stay tuned... More data in early March.

    Comparison of the TRAPPIST-1 system with the inner Solar System and the Galilean Moons of Jupiter.

    This diagram compares the orbits of the newly-discovered planets around the faint red star TRAPPIST-1 with the Galilean moons of Jupiter
    and the inner Solar System. All the planets found around TRAPPIST-1 orbit much closer to their star than Mercury is to the Sun, but as
    their star is far fainter, they are exposed to similar levels of irradiation as Venus, Earth and Mars in the Solar System.

    DRAGON: na cteni psanyho textu jsem odbornik:

    In contrast to our sun, the TRAPPIST-1 star–classified as an ultra-cool dwarf–is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system.
