Top Ten Planets Most Likely to Have Aliens

In the vast universe, after years of exploration, scientists have finally discovered more than 300 planets that may have life. They are called super earth. These terrestrial planets may have liquid water, and their environment is very similar to that of the earth. This is 10, the most famous and possible super earth.

Kepler 452b(Kepler 452b) is 1.6 times the diameter of the earth, and the earth similarity index (ESI) is 0.83, which is located in Cygnus, and is 1400 light years away from the earth. This is the first "livable" planet discovered around 20 15. It revolves around the same type of star as the sun and is close to the size of the earth. It may have an atmosphere and flowing water. It is called Earth 2.0, "the cousin of the Earth".

Kepler 62f is 1200 light years away. Discovered by Eric Agol, a professor of astronomy at the University of Washington. Planets are only 1.4 times larger than the earth, and they revolve around stars smaller and darker than the sun. Kepler 62f may be a rock surface. It receives about half as much heat and radiation from the stars as the earth receives from the sun. It may be completely covered by the ocean. If its density is the same as that of the earth, its mass may be 1.4 1 or 2.80 times that of the earth.

Kepler 452b and Kepler 62f are very similar to the Earth, but they are too far away. At the present level of science and technology, this can't be done in 40 million years.

Kepler 22b is the first planet suitable for human habitation. Its diameter is about 2.4 times that of the earth, and it is about 600 light years away. Although its diameter is much larger than that of the earth, its period of revolution is about 290 days, almost the same as the diameter of the earth. The central star revolving around it is very similar to the sun. It is also a yellow dwarf with spectral type G, but its mass is slightly smaller. The surface temperature of this planet is about 70 degrees Fahrenheit (equivalent to 2 1 celsius), which is very suitable for living, or it may be a warm ocean planet.

Kepler 186f is about 492 light years away from the earth, which is 1. 1 times the size of the earth. Its size is not only similar to that of the earth, but also close to the surrounding stars, which makes it possible for liquid water to exist on the surface. The various characteristics of the planet make it possible to have characteristics similar to those of the earth. Kepler 186f is the outermost planet in the Milky Way, which is located at the edge of the livable area, which means that its surface temperature may be too low and water may freeze.

Gliese 163C is about 7 times the mass of the earth. It may be a very big rock star or a small gas giant. Gliese 163c revolves around its dim star for 26 days, 50 light years away from the earth. Its star lies in the constellation Capricorn. Thierry Fouille, a Frenchman, reported this discovery at the General Assembly of the International Astronomical Union. Judging from the composition of the planet and the thickness of the atmosphere, it may support life.

HD855 12b is located in the constellation vela, orbiting the orange dwarf. According to the data obtained by HARPS, the mass of HD855 12b is 3.6 times that of the Earth, and the distance from the parent star allows liquid water to exist on the surface. Scientists say that the existence of liquid water is crucial to the formation of life. The cloud coverage of HD855 12b is at least 50%, which indicates that it can reflect enough energy into space to prevent the surface from overheating. Usually, the cloud coverage of the earth is 60%.

The semimajor axis of Gliese 667 Cc is only 0. 125 1 astronomical unit. It is 4.5 times the size of the earth. There are only 28. 155 earth days in a year on Gliese 667Cc. Gliese 667Cc is 85% similar to the earth. According to the thermal luminosity of the home star Gliese 667 C, Gliese 667 Cc receives 90% of the light from the earth. But most electromagnetic radiation is invisible infrared. According to the calculation method of blackbody temperature, Gliese 667 Cc absorbs more electromagnetic radiation, making its surface temperature (277.4K) slightly higher than that of the earth (254.3K) and closer to the "hot" edge of livable area.

The diameter of gliese 58 1g is about 1.2- 1.4 times that of the earth, and its mass is about 3. 1-4.3 times that of the earth. The average surface temperature is between -30℃ and-12℃. Period of revolution is the 37th Earth Day. The rotation period is equal, and the gravity is close to or slightly higher than that of the earth. The surface is composed of rocks, and there may be liquid water and atmosphere.

Gliese 58 1d is 20.3 light years away from the earth. Its mass is eight times that of the earth, and it is considered as a super earth. The team of scientists who discovered gliese 58 1d in 2009 determined that the planet was in a livable area through new observation results in late April 2009, which means that there may be liquid water or living things on the planet.

Gliese? 832c is a planet orbiting the stellar flasher 832, and its rotation period is 36 days. Its mass is about five times that of the earth. This may be the most exoplanet discovered so far, and it has the closest conditions to the earth. Astronomers believe that its temperature may be similar to that of the earth, with similar seasonality, its outer layer is surrounded by the atmosphere, and liquid water is allowed in the orbital environment.

On the other hand, no matter how many "super-earths" exist in the vast universe and how many planets humans can "carry their bags" directly, we should start from now on, from everyone's own, from small things, and protect our planet with the strength of all mankind, love nature and protect this beautiful, rich, quiet and peaceful blue planet!
