Asteroids: 'Potentially hazardous' asteroid bigger than a football pitch set to fly by

Asteroids: 'Potentially hazardous' asteroid bigger than a football pitch set to fly by

An asteroid known as 65717 (1993 BX3) is a true giant of the solar system. At 807 feet (256 metres), the asteroid is bigger than two football pitches laid length-to-length. NASA has revealed the space rock is whizzing through the solar system, and is set to make a close approach.

When the asteroid flies by, it will be travelling at a staggering 3.6 kilometres per second, or or almost 13,000 kilometres per hour.

The average space rock travels at a speed of anywhere between 11 kilometres per second, and 72 kilometres per second.

NASA's Juno Mission Expands Into the Future

The spacecraft, which has been gathering data on the gas giant since July 2016, will become an explorer of the full Jovian system – Jupiter and its rings and moons.

"Since its first orbit in 2016, Juno has delivered one revelation after another about the inner workings of this massive gas giant," said principal investigator Scott Bolton of the Southwest Research Institute in San Antonio. "With the extended mission, we will answer fundamental questions that arose during Juno's prime mission while reaching beyond the planet to explore Jupiter's ring system and Galilean satellites."

Reconstructing the solar system's original architecture

"The significant reorganization of the early solar system due to giant planet migration has hampered our understanding of where planetary bodies formed," said Jan Render, LLNL postdoc and lead author of the paper. "And by looking at the makeup of meteorites from the asteroid belt, we were able to determine that their parent bodies must have accreted from materials from very different locations in the early solar system."

Even though the asteroid belt is only a relatively narrow band of the solar system, it contains an impressively diverse collection of materials. For example, multiple spectroscopically distinct asteroid families have been identified within the main belt, indicating vastly different chemical compositions. In addition, meteorites are known to derive from roughly 100 distinct parent bodies in the belt, with diverse chemical and isotopic signatures.

Joliet Junior College Flips Switch on New Solar System | 1340 WJOL

Joliet Junior College has officially elevated its sustainability footprint, announcing the completion and activation of its 1.3 megawatt (MW) onsite solar system at Main Campus. The solar array, which consists of 3,542 solar panels, was installed by national solar developer Pivot Energy and will save the college more than $1.6 million in electricity expenses over 25 years

The panels were provided by retired Joliet oncologist Dr. Sarode Pundaleeka with Sunlarge Industries. Over the first 10 years, JJC will pay a reduced rate for the energy generated by the panels, after which they will be donated to the college.
