Jakarta, CNBC Indonesia – Astronomers have found habitable planets that are similar in size to Earth and 300 light-years away. This was observed from NASA’s Kepler Space Telescope.
According to a recent study, it revealed that of the 2,681 exoplanets seen by the Kepler mission that operated in 2009 and 2018, the planet named Kepler-1649c was the most similar in size and temperature to planet Earth.
Despite Kepler’s mission being retired in 2018, the data can still be used to produce more discoveries in the coming years. Currently, NASA’s Transiting Exoplanet Survey Satellite (TESS) mission is the last planet hunter to search for exoplanets.
The planet Kepler-1649c is 1.06 times larger than Earth and about 75% of the amount of light Earth receives from the sun. This shows that the planet’s surface temperature can be similar to that of Earth.

“The world is interesting and this gives us greater hope that a second Earth is among the stars, waiting to be discovered,” Thomas Zurbuchen, associate administrator at NASA’s Scientific Mission Directorate in Washington, quoted by Space.com , (4/16/2020).
“Data collected by missions such as Kepler and our Exoplanet Transit Satellite Survey (TESS) will continue to produce extraordinary discoveries as the scientific community improves its ability to search for promising planets year after year,” he added.
According to Zurbuchen, there is still much unknown about Kepler-1649c, including its atmosphere. The calculations in terms of size can be confused because the object under study is very far away, but according to what is known, Kepler-1649c is very interesting for scientists looking for a world with potentially habitable conditions.
“Of all the planets that are incorrectly labeled, this [kepler-1649c] very interesting Not only because it is in a habitable zone and the size of the Earth, but because of how it can interact with neighboring planets, “said Andrew Vanderburg, a researcher at the University of Texas.
“If we don’t take the algorithm seriously, we will miss it,” he said.
