Summary: Sriharikota (Andhra Pradesh) [India], Apr 1 (ANI): The Indian Space Research Organisation's PSLVC-45 successfully injected electronic intelligence satellite EMISAT along with 28 international customer satellites into sun-synchronous polar orbit on Monday.
By combining these two pieces of information they were able to establish that the dust ring was consistent with a perfectly polar orbit. This means that while the stellar orbits orbit each other in one plane, like two horses going around on a carousel, the disc surrounds these stars at right angles to their orbits, like a giant ferris wheel with the carousel at the centre.
