This is the third blog that I am writing on this topic and we
have reached up to the year 2050 and the events that will happen on the years
before. In this blog, I’ll explain some more events that will happen
before 2100 soon, I will write blogs about more years into the future. In 2061,
Halley’s comet will flyby close to Earth and surprisingly, it will be visible
to the naked eye. This comet was discovered in 1758. It has a diameter of about
11 km and has a mass of 220 trillion kg. This comet will flyby above Earth on
28th July 2061. This comet may collide with planet Earth and if that
happens, it will collide with a large amount of force and will form a huge
impact crater that would be rough, 33 km deep and 89 km wide. The impact of
this collision will kill everything within a range of 238 km. Moreover, a
few days after the collision, dust clouds will take over the sky and prevent
light from Sun from reaching us. This will start a nuclear winter, which
will kill most of the species that inhabit this planet as well as most of the
humans.

A few years later, in 2069 NASA will send a probe to Alpha Centauri,
which is the closest star system to us. This star system consists of three
stars named as Alpha Centauri A, Alpha Centauri B, and Alpha Centauri C. Even
though it is the closest, it is still approximately 4.21 light-years away from
us which means that even light from this star system takes 4 years to reach us
which, trust me, is a very long distance. As we know, the Voyagers are
traveling in outer space at very high speeds of about 15.4 km/s, it will still
take it tens of thousands of years to reach the star system. This probe will
search for life on the planets that orbit these stars and will also confirm if
the conditions of them are good enough to sustain human life. Though it will
take a lot of time for us to reach the star system with the technology of
today, we may find a way to travel faster enough to reach it in a few years.
This blog was another of the topic of the events that will
happen before 2100. After this one, I will write the last blog of this series
and later, I will write about the events that will happen in a few more years
into the future.
