APOD: 2020 August 18 Б TYC 8998 760 1: Multiple Planets around a Sun Like Star
Explanation:
Do other stars have planets like our Sun?
Previous evidence shows that they do, coming mostly from
slight shifts in the star's light created by the orbiting planets.
Recently,
however, and for the first time, a pair of
planets
has been directly imaged around a Sun-like star.
These
exoplanets orbit the star designated
TYC 8998-760-1 and are identified by arrows in the
featured infrared image.
At 17 million years old, the parent star is much younger than the 5-billion-year
age of our Sun.
Also, the
exoplanets
are both more massive and orbit further out than their
Solar System analogues:
Jupiter and Saturn.
The exoplanets
were found by the
ESO's
Very Large Telescope in
Chile by their
infrared glow Б
after the light from their parent star was
artificially blocked.
As telescope and
technology improve over the next decade,
it is
hoped that planets more
closely resembling our
Earth will be
directly imaged.
