NASA's "Parker Solar Probe" spacecraft becomes the closest ever sent to the sun, by passing 42.7 million km (26.6 million miles) from the sun's surface. The previous record was set in 1976 by the "Helios 2" spacecraft. Parker's elliptical orbit will eventually take it to within 6.1 million km (3.8 million miles) of the sun.

Astronomers announce that 2014 UZ224 is the third most distant Solar System object known from our Sun, currently over 90 times the Earth's distance from the Sun (90.8 AU or 8.44 billion miles), after Eris (96.2 AU) and V774104 (~103 AU).

Scientists at Northumbria University in northeast England develop a computerized statistical model of the Sun's solar cycle (a measurement of the number of sunspots and solar flares, in this case between 1976 and 2008, and their intensity and activity). While preliminary, and not yet peer-reviewed, the data predicts irregularities in the cycle: the Northern Hemisphere could experience a slight lowering in temperatures in the 2030s.

New data from the NASA space probe MESSENGER indicate that Mercury, the closest planet to the Sun, almost surely has water ice buried beneath the surface at its north pole.

An unusually large coronal mass ejection emitted by the Sun barely missed the Earth by nine days, dubbed the Solar storm of 2012. If it hit, it would have caused up to US$2.6 trillion in damages to electrical equipment worldwide.

Astronomers using the Wide-field Infrared Survey Explorer telescope identify a Trojan asteroid, calling it "2010 TK 7 ", orbiting on the same path as the Earth around the Sun. The rock poses no danger to the Earth since it sits in a what is termed a gravitational "sweet spot".
