Space Terms to know about
Supernova :
A supernova is a powerful and
luminous explosion of a star. It has
the plural form supernovae or
supernovas, and is abbreviated SN
or SNe. This transient astronomical
event occurs during the last
evolutionary stages of a massive
star or when a white dwarf is
triggered into runaway nuclear
fusion.
Exoplanet :
An exoplanet is any planet beyond
our solar system. Most orbit other
stars, but free-floating exoplanets,
called rogue planets, orbit the
galactic center and are untethered
to any star.
Barycenter :
In astronomy, the barycenter is the
center of mass of two or more
bodies that orbit one another and
is the point about which the bodies
orbit. A barycenter is a dynamical
point, not a physical object. It is an
important concept in fields such
as astronomy and astrophysics.
