be extrapolated back into the past or forward into the future, they are subject to increasing significant cumulative errors over very long periods. Inaccuracies of these measured parameters make determining the true minimum distances of any encountering stars or brown dwarfs fairly difficult. One of the first stars known to approach the Sun particularly close is Gliese 710. The star, whose mass is roughly half that of the Sun, is currently 62 light-years from the Solar System. It was first noticed in 1999 using data from the Hipparcos satellite, and was estimated will pass less than from the Sun in 1.4 million years. With the release of Gaia's observations of the star, it has since been refined to a much closer , close enough to significantly disturb objects in the Oort cloud, which extends out to from the Sun. The second-closest object known to approach the Sun was only discovered in 2018 after Gaia second data release, known as 2MASS J0610-4246. Its approach has not been fully described due to it being a distant binary star with a red dwarf, but almost certainly passed less than 1 light-year from the Solar System roughly 1.16 million years ago. Gaia third data release has provided updated values for many of the candidates in the table below.
