Tomorrow for me, today for others, there will be a Close Encounter with Enceladus .....
Meanwhile, closer to our home planet.......Oct 27, 2015:
Over 980 million miles or about 1.6 billion kilometers from home, NASA’s Cassini spacecraft hurtles through the starry expanse of space. From its vantage point orbiting Saturn, Earth is nothing more than a miniscule pinprick of light not unlike the stars framing the gorgeous ringed planet.
Cassini has been orbiting Saturn since 2004, and it has made dozens of flybys of Saturn’s intriguing moons. Its next close encounter with Enceladus on October 28, 2015 promises potentially exciting results.

Play the video on the space.com page to see how close it looks.An asteroid the size of a football stadium will zoom past Earth on Halloween, in a close encounter that astronomers view as far more treat than trick.
The massive asteroid 2015 TB145 will come within 310,000 miles (500,000 kilometers) of the planet — or about 1.3 times the distance from Earth to the moon — on the afternoon of Oct. 31, just three weeks after the space rock was discovered, according to NASA. There's no threat of an impact on this pass, NASA officials said.
Astronomers estimate the diameter of 2015 TB145, which is also known as "Spooky," to be between 950 feet and 2,130 feet (290 to 650 meters). The Halloween flyby will mark the closest known encounter with such a big asteroid until August 2027, researchers said. [Potentially Dangerous Asteroids (Images)]

Three weeks! On this pass!
Lets not forget the last close encounter when an interloper not known at the time exploded over Russia, remember Chelyabinsk?
Start thinking on an even bigger scale. Realize that the universe has not stopped expanding and may never stop. Much like history and evolution, the expansion of the universe is never ending. Regarding evolution, it does not only exist as we know it.
That 980 million miles is not even the equivalent of a mouth full of saliva in all of the oceans on this planet.
Another comparison to ponder. Take into count all of the insects, ie; ants, termites, flies, bees and so on, and compare their numbers to the population of the human race. If ever the non-human inhabitants on the planet were to wage war on mankind who do you think would survive?
This YouTube vid Powers of Ten from 1977 shows cosmic zoom from 10^24 to 10^(-16) metres.
Oct 31, 2015:
When the Space Age began, there was no such thing as a “graphical user interface.” Astronauts interacted with their electronics using only knobs and toggle switches. It was a different time. Fast forward to 2015.
The knobs and switches of the 1950s have been replaced by a glass cockpit, where the majority of commanding is done through software controls. Old-fashioned twisting and flipping may soon be replaced by a complex combination of taps, swipes, and finger-tip swirls.

Great program Bill, I've been using it since v0.11.4 (2012-08-25) I'm now up to v0.13.3 there have been bug reports about some rendering problems, but I haven't noticed any on my lowly i3 Intel even though Stellarium complains about it in the logs.
Your link to the Stellarium page offers the latest stable version 0.14.0. Windows users, make sure when downloading to use the proper 32 or 64 bit rate for your version of Windows.
Overview of version 0.14.0 with some already known bugs
