READ HIGHLIGHTS 

The Very Large Telescope of the European Southern Observatory was utilised by astronomers.

At a distance of 4 million kilometres, the planet circles Proxima Centauri.

On Earth, it takes 5 days to complete a full orbit of the star.

WHY IN NEWS 

A new planet has been found circling Proxima Centauri, the nearest star to the Sun, by a team of scientists. Proxima d is the third planet identified in the constellation, and it is one of the smallest of the planetary systems found so far. Proxima d is only a fourth the mass of The earth and circles its parent star at a distance one-tenth that of the Sun and the Planetary Port's closest moon, Mercury. As a result, the alien world is only a few light-years away from Proxima Centauri, which is around four light-years distant from our solar system. This exoplanet was discovered by scientists using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile. At a distance of around four million kilometres, the planet circles Proxima Centauri.

 However, it is not exactly friendly. It is too near to the star and the habitable zone to have liquid water. On Earth, it accomplishes a stable orbit of a star every five days, according to observations.   Proxima d is the third exoplanet discovered in the Alpha Centauri constellation, while one was discovered in 2016. Proxima b has attracted scientists' interest since it was around the same size as Earth, had a rocky surface, and a temperature appropriate for liquid water — all of which made it possibly livable. Proxima c, the second potential planetary, has a 5 rotation around the star. The first signs of the presence of candidate planet Proxima c, according to the researchers, appeared in 2020 when they were watching Proxima Centauri to confirm the existence of Proxima b.

The discovery was reported in the Astronomy & Astrophysics journal.  In a statement published by the ESO , lead author Joao Faria said, 'The finding demonstrates that our closest stellar neighbour appears to be crammed with exciting new planets, within range of more research and potential exploration.'  The achievement was substantial because it proved that doppler shift method had the ability to expose an inhabitants of light planetary systems earthlike, which are thought to be the most plentiful in our universe and competent of going to host living as humans know it, according to Pedro Figueira, ESPRESSO instrument scientist at ESO in Chile.  They verified its presence with additional observations.
