Sackler Astronomy Lecture: The Search for Planet Nine
Δημοσιεύτηκε στις 1 Μαρ 2017
Recent
evidence suggests that a massive body is lurking at the outskirts of
our solar system, far beyond the orbits of the known giant planets. This
object, at a distance approximately 20 times further than Neptune and
with a mass approximately 5000 times larger than Pluto, is the real
ninth planet of the solar system. In his lecture, Mike Brown talks about
the observation that led his team to the evidence for this Planet Nine
and discusses how so massive an object could have been hiding in the
outer solar system for so long. He also discusses the international
effort to pinpoint this newest member of our planetary family.
Mike
Brown is the Richard and Barbara Rosenberg Professor of Planetary
Astronomy at the California Institute of Technology, specializing in the
discovery and study of bodies at the edge of the solar system. He is
best known for his discovery of Eris, the most massive object found in
the solar system in 150 years, which led to the debate and eventual
demotion of Pluto from a real planet to a dwarf planet. In 2006 he was
named one of Time Magazine's 100 Most Influential People and was
inducted into the National Academy of Sciences in 2014.
