From March 2026.

Today's 2 topics:

- Once every 1,435 days , a 780 foot diameter space rock, 2017
TC1, that my Catalina Sky Survey teammate Carson
Fuls discovered makes an annihilation defying close
approach to our star. At it's nearest point to the Sun, Carson's
well done space rock is traveling at an amazing 93 miles per
second and receives 26 times the amount of solar radiation that
heats the surface of the planet Mercury to 800° F. After Carson
first discovered his heat resistant space rock traveling towards
it's next hot date with the Sun, it was observed by telescopes in
New Mexico, Arizona, Hawaii, and England.

 

- The orbits of the planets are closely aligned with the
extension of the Sun's equator into space and are contained
within the flattened disk of material which forms the plane solar
system. Most asteroids have orbits with inclinations or tilts to
the solar system's plane which are less than 20 degrees. Thus,
when my Catalina Sky Survey teammate Rose
Matheny discovered 2017 TF4, a small space rock which
soars into the lonely space high above and below our solar
system's plane, it got our attention. As with all of our asteroid
discoveries, Rose had no idea of what kind of object she had
discovered with our Schmidt Telescope on Mt. Bigelow, Arizona
until it had been tracked by observers around the world.

Mein Archiv

Deine Privatkopie der Folgen, die du nicht verlieren willst.

Podcast-Folgen verschwinden. Feeds werden auf die letzten Episoden gekürzt, Hoster räumen alte Dateien ab, Formate wechseln den Anbieter und lassen ihr Archiv zurück. Mit „Mein Archiv“ sichert podcast.de die Folgen deiner Podcasts für dich — angefangen bei den ältesten, denn die sind zuerst weg.

  • Deine gesicherten Folgen bleiben hörbar, auch wenn das Original offline geht.
  • Auch Folgen, die im heutigen Feed gar nicht mehr stehen — podcast.de kennt sie noch.
  • Herunterladen bleibt möglich, solange die Folge beim Podcaster liegt. Der zählt seine Abrufe wie bisher.
