But still I would prefer some model which estimates e.g. an analytic shape of radial distribution function from first principles (from some theory of star formation), rather than estimate … Webb3 juli 2024 · It's very distant from us, with an inner boundary 10,000 times the Sun-Earth distance. At its outer "edge," the cloud stretches into interplanetary space some 3.2 light-years. For comparison, the closest star to us is 4.2 light-years away, so the Oört Cloud reaches almost that far. Planetary scientists estimate the Oort Cloud has up to two ...
