Voyager 1 reaches 100 AU

An Astronomical Unit (AU) is the distance from the earth to the sun (93 million miles).


In 30 years, Voyager 1 has traveled to a distance of 100 AU from the Sun, farther than any other known man-made object; around 9.3 billion miles from our sun.

The spacecraft cannot rely on solar power anymore; it’s too far out. At this distance, our sun appears merely as a bright point of light. The craft is getting power from nuclear power sources, called radioisotope thermoelectric generators, provided by the US Department of Energy.

In the image to the left, Voyager 1 is now at the outer edge of our solar system, in an area called the heliosheath. This is a place where our sun’s light and gravity wanes. It is approaching interstellar space, traveling at about 1 million miles per day.

In 10 years, Voyager could cross into interstellar space.

About Michael Coates
I am a pragmatic evangelist. The products, services and solutions I write about fulfill real-world expectations and use cases. I stay up-to-date on real products I use and review, and share my thoughts here. I apply the same lens when designing an architecture, product or when writing papers. I am always looking for ways that technology can create or enhance a business opportunity .. not just technology for technology's sake. My CV says: Seasoned technology executive, leveraging years of experience with enterprise and integration architectural patterns, executed with healthy doses of business acumen and pragmatism. That's me. My web site says: Technology innovations provide a myriad of opportunities for businesses. That said, having the "latest and greatest" for its own sake isn't always a recipe for success. Business successes gained through exploiting innovation relies on analysis of how the new features will enhance your business followed by effective implementation. Goals vary far and wide: streamlining operations, improving customer experience, extending brand, and many more. In all cases, you must identify and collect the metrics you can apply to measure your success. Analysis must be holistic and balanced: business and operational needs must be considered when capitalizing on a new technology asset or opportunity.
