The lead author of the study. Anthony Jenova, a researcher at the Goddard Space Flight Center at NASA's Goddard Space Flight Center. Antonio Genova said in a statement. Mercury is the closest planet to the sun, which makes it sensitive to the star's gravity.
As Einstein said, large objects such as the sun will distort the space-time continuum. The bigger the mass, the larger the gravitational force, the smaller the orbit of the planets will be, and vice versa.
Scientists have used radio tracked data to determine the difference in Mercury's position, and they found that Mercury clearly shows signs that planet orbit is expanding. It shows that the sun's gravitational attraction to mercury is weakening.
But the changes in the sun have little influence on people and do not affect daily life.
