Is there another planet like Earth? Science has experienced amazing growth in the last 5 decades and our knowledge of space is increasing daily and we are discovering new planets, stars, black holes, and much more. Our curiosity to explore space increases day by day and some reports say that there are around 300 million habitable planets in our Milky Way alone. In 2021, there are 4,843 confirmed exoplanets. Here below we mention 10 Earth-like planets that could be the future Earth. We have not given any specific order to the planets because each one is unique.
The 10 Most Earth-like Alien Planets:
10. TOI 700 d
TOI 700 d is an exoplanet located in the habitable zone of its star TOI 700, which is a cool “M Dwarf”. Located 100 light-years away in the constellation Dorado. The TOI 700 has only 40% of the solar mass and size and only half the temperature of its surface. The star shows no signs of harmful “star flares” that would make life impossible on orbiting planets.
TOI 700 d is a tidal-locked planet, which means that one side always faces the star and the other side lives in darkness all the time. The planet is likely known to be rocky and is 20% larger than Earth and receives 86% light from the star compared to the Earth it receives from the Sun.
9. TRAPPIST-1e
TRAPPIST-1 is a dwarf planet almost 40 light-years away. Seven known Earth-like planets in this star system and the entire system were discovered in 2017. It is the only known solar system to have 7 Earth-like planets orbiting a single star. There are 3 habitable planets in this system and all three are probably known to be rocky planets.
TRAPPIST-1e is very likely similar to Earth in terms of size, mass, and temperature. TRAPPIST-1e has 93% gravity at the earth’s surface and is probably known to harbor liquid water and terrestrial life. The other planets in the solar system are known to be entirely aquatic worlds or covered with thick layers of ice.
8. Proxima Centauri B
Proxima Centauri B is an exoplanet located in the habitable zone of its red dwarf star Proxima Centauri; Which is the closest star to our Sun and belongs to a triple star system. Proxima Centauri is only 4.25 light-years distant from us. The star is so dim that you cannot see it with the naked eye, although it is the closest known star to the Sun. Proxima Centauri B is known to be an Earth-like planet, but the chances of sustaining life on the planet are slim. As the exoplanet receives 2000 times more stellar winds from its parent star compared to Earth.
The planet is supposed to be tidally locked to its parent star and one side could be icy and the other extremely hot.
7. ROSS 128 b
Ross 128 b is an exoplanet that orbits the red dwarf star Ross 128, located 11 light-years from us. The exoplanet is considered one of the most suitable candidates for the Earth of the future. As it is only 35% more massive than Earth and only 38% more starlight, which makes it is suitable to host liquid water and also an atmosphere. The host star Ross 128 is only 17% of the mass and 20% of the radius of our Sun. The exoplanet Ross 128 b is very close to its star and completes its orbit around the star in about 9.9 days.
6. GLIESE 581g
Gliese 581g is another habitable exoplanet located 20 light-years from us. But there is a doubt about the existence of the planet. To confirm the existence of a planet, two independent studies are necessary and the first study was conducted in 2010. The planet orbits its parent star Gliese 581, which is a dwarf star and is much cooler than our Sun. Some research mark the existence of the planet and others do not. So let’s look forward to a more accurate investigation in the future.
5. Kepler-22b
Kepler-22b is an exoplanet located 600 light-years away from us, confirmed in December 2011. It was the first confirmed exoplanet in the habitable zone. It is 2.4 times larger than Earth and also orbits a sun-like star with a suitable temperature of 22 ° C (72 ° F), making it a suitable planet for living. Scientists have doubts as to whether the planet is watery, gaseous, or rocky, but they have confirmed the cloudy atmosphere. Since it is almost twice the size of the earth and we can expect a very rocky core.
4. Kepler 452b
Kepler 452b is an exoplanet that orbits a G2-type star and is located in the habitable zone whose mass may contain liquid water on its surface. The exoplanet is 60% larger than Earth and is considered rocky. The exoplanet completes one orbit in 385 days, and the exoplanet is slightly older than our Earth. It is known to be the most suitable habitable planet like Earth and also an older cousin of Earth. The parent star is 1.5 billion years older than our Sun and 10% larger. The exoplanet is 1400 light-years from us in the constellation Cygnus.
3. Kepler 186f
The exoplanet is 500 light-years from the constellation Cygnus. Kepler 186f is also known as second earth and is only 10% larger than earth. It is in the habitable zone of its parent star. This exoplanet could have a suitable temperature to contain liquid water on its surface. The planet completes one orbit in 130 days and receives ⅓ light from its star compared to the light the Earth receives from the Sun.
2. KOI 7711.01
KOI 7711.01 is another candidate for harboring life. It is 1700 light-years distant and orbits a star similar to the Sun. It is located in the habitable zone and may contain liquid water. But scientists are still confused about what kind of atmosphere it has. Furthermore, the exoplanet is 30% larger than our Earth.
1. Kepler 62e
Kepler 62 is a solar system located 990 light-years away from us. And Kepler 62e is in the habitable zone of its parent star. It is known to be a water world. Furthermore, it is about 1.6 times the size of the earth. And the exoplanet is supposed to have cloudy skies and a warm temperature. It orbits its star in 122 days. We can also call it a mini Neptune. As most of the part is covered in water with minimal land area, which makes it more interesting to see.
