HD by Dominique Naef of the Geneva

HD 80606 b is an exoplanet
discovered in 2001 by a team led by Dominique Naef of the Geneva Observatory in
Switzerland.

HD 80606 b is around 190.4 light
years away from Earth and is thought to be around 7.6 billion years old.

This planet is known for its
strange elongated orbit around its host star, similar to the orbit of a comet,
with distances from its star ranging from 79 million miles and only 2.8 million
miles. This orbit around HD 80606 (a sun-like star) lasts around 111 days. During
this extreme orbit, the planet experiences significant weather changes. HD
80606 b’s host star, HD 80606, is joined in space to a similar star called HD
80607.Kapteyn b is an extrasolar planet
that orbits a red dwarf star named Kapteyn at a distance of around 0.17 AU. It
was discovered in 2014 at the European Southern Observatory in Chile.This planet is located
approximately 12.8 light years away from Earth, and it is approximately 11.5
billion years old.

Kapteyn b is known as one of the
first discovered potentially habitable planets. The solar system it is in,
orbiting Kapteyn’s star, also contains another planet called Kapteyn c, but
this planet is considered to be too cold to sustain life. Kapteyn b orbits the
Kapteyn’s star every 48.6 days, and it is inside the habitable zone of this
solar system. Depending on the atmosphere of the planet, it may be able to
sustain water and it is thought by scientists to have a rocky surface.Messier 31, also known as the
Andromeda Galaxy is a spiral galaxy located in the constellation Andromeda. It
was once known as the Great Andromeda Nebula. It was first seen a very long
time ago, but confirmed with technology in the 1900’s.This galaxy is located
approximately 2.54 million light years away from Earth and thought to be formed
10 billion years ago.

The Andromeda Galaxy is the closest
Galaxy to ours and can be observed from Earth at night by the naked eye. It is
a huge galaxy, presumably containing many black holes and over a trillion
stars. Interestingly, scientists estimate that Andromeda is possible to collide
with the Milky Way Galaxy in 4.5 billion years, and perhaps form a new galaxy together.
8 billion years ago, the Antromeda Galaxy experienced a similar collision in
order to form the galaxy it is today.The Cartwheel Galaxy is a deep
space or deep sky galaxy discovered in 1941 by Fritz Zwicky. It is located in
the constellation Sculptor, and it is named the “Cartwheel Galaxy” because it
looks similar to a wagon wheel. The Cartwheel Galaxy is located around
500 million light years from our solar system. Its age is not exactly known but
it is thought to have formed its current shape 200 million years ago.

This Galaxy is slightly larger
than ours, with a span of 150,000 light-years. It is thought to rotate at a
speed of around 217 km per second. Around 200 million years ago, it collided
with another galaxy, causing it to form an abnormal shape. Previous to this
collision, the galaxy was formed in an ordinary spiral. It is thought to be
slowly retaking the form of a spiral galaxy.Messier 64, also known as The
Black Eye Galaxy  was discovered in 1779
by Edward Pigott. It is located in the constellation Coma Berenices and has a
diameter of approximately 56 thousand light-years.The Black Eye Galaxy is located
around 17 million light-years from EarthThis spiral galaxy is known for
its strange motion, looking as though some objects/gasses in the galaxy are
moving in opposite directions. This strange motion is thought to possibly have
been caused by a previous collision with another galaxy. This galaxy has a
third name, “Sleeping Beauty Galaxy” because of how the dust in the galaxy
seems to hide the stars. This dust also appears as a dark band in the galaxy,
coining the name “black eye” galaxy.

                As
astronomers have pieced together an abundance of information about objects in
our solar system, in our universe and outside our universe. The objects
described, including 243 Ida in our solar system, HD 80606 b outside of our
solar system and Messier 31, a galaxy outside of our own, have lead to future
astronomical discoveries. However, there is still an unlimited amount of
information left to identify, as past theories and sightings point to new
discoveries.
