    793 Close Space Rock

    793 Close Space Rock

    Perhaps the most dangerous Amor asteroid is 2006 HZ51 .It was discovered by my team the Catalina Sky Survey.  Fortunately the closest 2006 HZ51 will come to our home planet is  June 11 of 2116 when it will pass us harmlessly 26 times the distance to our moon away from us.

    280E-294-Dangerous Duo

    Recently in the space of 28 hours my Catalina Sky Survey teammates Rose Matheny and Carson Fuls discovered two Potentially Hazardous Asteroids to add to the list of the more than 1700 which asteroid hunters have discovered. Fortunately, none of the Potentially Hazardous Asteroids are currently on a collision course with planet Earth.

    792-Closest Approaching Comet

    P/1999 J6 (SOHO) was discovered 10 May 1995 by Mike Oates as part of the Citizen Science Sun Grazer Project in which volunteers from all over the world have the chance to discover a comet in images taken by the Solar and Heliospheric Observatory or SOHO for short.RADAR studies of the daytime Arietid ( AIR-ee-uh-tids) meteor shower stream which peaks every June 7 indicates that  P/1999 J6 (SOHO) could be one of the potential parent objects.

    279E-293-From Luna

    More than 240 Lunar meteorites have been found in the Dhofar region of Oman, on the LaPaz Icefield of Antartica, and other locations on the Earth's surface. These space traveling rocks were blasted from the Moon's surface by the impact of asteroids and comets which accelerated them to speeds greater than the lunar escape velocity of 1.5 miles per second. Subsequently these interplanetary travelers in the night orbited the Sun for an extended period of time before entering our atmosphere and falling to Earth. We know these meteorites are from the Moon because they contain mixtures of atoms which are found on the Moon but not in Earthly rocks.

    791-A Fireball and It’s Gifts

    It all started when Krisztián Sárneczky at the Konkoly Observatory near Budapest, Hungary reported the position and brightness of an unknown asteroid rapidly moving through the constellation of Lynx. Three hours later , the object, now called 2024 BX1 exploded harmlessly in our atmosphere

    278E-292-Disintegrating Comet

    278E-292-Disintegrating Comet

    Comets are made up of organic materials and ices of various substance which are left over from the formation of our solar system 4.6 billion years ago. When the gravity of a nearby star or other object changes one of these dirty snowball's orbit, its path can bring it into the inner solar system and thus near enough for the Sun to affect it and for us to study what is going on.
