Binary Aten asteroid (66391) 1999 KW4 and its minor-planet moon make their closest-ever recorded flyby of Earth at 3.2 million miles away. The asteroid will approach even closer at 0.0155 AU (2,320,000 km) from Earth in 2036, and is the largest asteroid to approach Earth until (4953) 1990 MU in June 2027.
NASA astronomers use the Hubble and Spitzer space telescopes in research implying that "hot Saturn" (high surface-atmosphere temperatures and gas giant-mass) exoplanet WASP-39b, located 700 light-years from Earth, has a large amount of water molecules in its atmosphere.
