There are over 100 billion galaxies in the universe.
People honestly find it weird when I tell them that there may be other individuals like us in space. Please understand that there are over 100 billion galaxies in the universe; we, humans, are part of just one. There must be planets like Earth out there in other galaxies too, and there must be individuals similar to us residing in one of those undiscovered planets. I am certain scientists and astronomers will come up with a plan in the forthcoming years to locate them. Being a curious human, you should always have an open mind when things as such are being addressed or discussed.
In this particular article, I am going to talk about 5 Earth-like planets that have been discovered so far. We know that scientists are preparing a group of people for a mission to Mars; they just want to see if we can somehow make it our home in the future. The resources on earth are unfortunately limited and would one day end. Hence, the mission to explore Mars is nothing but a backup plan to save humans from being extinct.
Discovering aliens has been a massive dream of ours, I must confess. The scientists have so far stumbled upon almost 2000 planets that seem like earth. More than half of these discoveries have been made by NASA’s Kepler space telescope, which launched in 2009 on a mission to learn how common Earth-like planets are throughout the Milky Way galaxy.
According to Kelper’s discoveries, there are multiple small rocky worlds like Earth in the galaxy. We, however, do not have sufficient resources to learn more about them. The situation may change in the forthcoming years, though.
Here are 5 Earth-like planets you probably did not know about:
This particular exoplanet, which is just 22 light-years far from the Earth, is at least 4.5 times as massive as Earth. Gliese 667Cc completes one orbit around its host star in approximately 28 days; the star is a red dwarf and is considerably cooler than the sun. Hence, the said exoplanet lies in the habitable zone.
Kepler-22b is about 600 light-years away from planet Earth. It was the first planet found in the habitable zone of its parent star, but the world we are talking about is quite larger than Earth. Scientists have no idea if this super-planet is rocky, liquidy or gaseous. However, we do know that its orbit is about 290 days long.
Kepler-69c is approximately 2,700 light-years away from Earth and is considered to be at least 70% larger than Earth in size. The said planet completes one orbit every 242 days, making its position within its solar system. Kepler-69c’s host star is about 8% as bright as the sun, so the planet seems to be in the habitable zone.
This particular planet is about 40 times larger than Earth and orbits a star much cooler than the sun. Its 267-day orbit puts Kepler-62f squarely within the habitable zone. Moreover, it lies about 1,200 light-years away from Earth.
All in all, this universe is massive, and there is a lot to explore. We do not have sufficient resources at the moment, but I am certain things will change in the forthcoming years.
