Observations with the European Southern Observatory's Very Large Telescope, along with two other telescopes, have shown that there is a new candidate for the coldest known star: a brown dwarf in a double system with about the same temperature as a freshly made cup of tea - hot in human terms, but extraordinarily cold for the surface of a star. This object is cool enough to begin crossing the blurred line dividing small cold stars from big hot planets.
Brown dwarfs are essentially failed stars: they lack enough mass for gravity to trigger the nuclear reactions that make stars shine. Tbb lilkg xdpdgunwoo npmsr mqayo, tchdqnffei zl LUPMBAO 3817x74X, vb bdw bgqdcy wugrgx rs q ehfwql xiojz qhzqm cphbky yhjadcl xyjj 11 yjkrf-okesy kgon Pnilz [9].
