With a diameter of approximately 12,750 kilometers, Earth is the largest of the four rocky planets (Mercury, Venus, Earth and Mars) in our solar system. While Neptune has a diameter of approximately 49,250 kilometers, or four times larger than Earth, it is the smallest of the four gas planets (Jupiter, Saturn, Uranus and Neptune).
Recently, astronomers from the University of Bern in Switzerland revealed that using the Atacama Large Millimeter/submillimeter Array-ALMA radio telescope network, they discovered six planets 100 years from Earth. Light in orbit relative to the sun It states that these 6 planets are planets larger than Earth but smaller than Neptune. Astronomers suspect that these stars might be rocky planets with thick hydrogen and helium atmospheres. Its body was made of rock and ice. Is there a warm atmosphere and water or something else? Interestingly, they may also provide insights into the birth and evolution of planetary systems. Because they are the most common type of planet in our Milky Way galaxy.
This type of planet is 2-3 times larger in diameter than Earth’s but smaller than Neptune. and orbits closer to its star than the innermost planets of the solar system. The way Mercury orbits the sun Even their basic nature remains a mystery. But astronomers have identified the six newly discovered planets as They are 1.9 to 2.9 times the diameter of Earth orbiting their parent star HD110067. They are visible in the night sky in the constellation Berenice I.
