While there is no need to worry about our sun destroying any of the planets in our solar system any time in the near future, the newly-discovered star is providing scientists with new information about the evolution and life cycle of star systems. Their extreme similarity to the Sun make these so-called solar twins ideal targets for investigating the connections between stars and their planets. Scientists believe, it may have swallowed one or more of its planets, based on lithium and refractory elements recently discovered near its surface. The parallels between this star and our own obviously beg the question of whether Earth will one day face a similar fate as these unfortunate exoplanets; for now at least, the team can't say one way or the other whether this is a normal outcome of the planet formation process around stars like this.
In one of his statements reported by CBC News, study co-author Jacob Bean said that the good thing with their discovery is that it also shows that this doesn't mean that the sun will "eat" the Earth any time soon. We've identified about 2,000 exoplanets over the course of the last two decades, but it's not common to find ones orbiting stars that resemble our own Sun - when we do, we call them "solar twins", and it's these stars that are most optimal to study.
Stars are also known as solar twins due to their closeness and resemblance to Sun.
As said by another co-author of the study, Megan Bedell, it is quite impossible to draw any conclusion on the basis of a single mission or clue and hence we are taking on the mission forward for more facts and explorations.
In 2015, the research team discovered its first exoplanet using the 3.6-metre telescope at La Silla Observatory in Chile.
The discovery was part of a multi-year project aimed at discovering planets that orbit solar twins. Instead, they probably migrated inward from the outer parts of the planetary system. As a result, when a star engulfs a planet, the lithium that the planet deposits in the stellar atmosphere stands out. This is because they are in very tight orbits around the star and have moved inwards from where they were before. Maybe Earth will be on the chopping block in a billion years. It features four times the amount of lithium expected for a star its age, evidence it has ingested a few planets in its recent past. Already there are projections that Sun may swallow up Mercury and Venus. If a cat is seen sitting next to a canary's cage with yellow feathers in its mouth, it is pretty well certain the cat ate the canary. Astronomers while experimenting on the sun, termed as "HIP68468", discovered it destroying the planets coming to its orbiting trail, a discovery that can trigger many hidden secrets of the planetary system of the cosmos.
This solar twin is dubbed HIP68468.
