OK, this is not cannon to the TV show or film, but it would make an interesting addition and is factually sound.
Over viewThe Universe is a gigiantic space filled with stars and galaxies, this is also the type of space our solar system as well as the earth is in. But how will the universe look like without people?
Opportunity continues to explore Mars, sending information that will never be seen on Earth.

On Earth all cities go dark. Weather satellites still orbit the earth at a height of 510 miles. Their solar panels will keep them running for decades but the ground stations they send their data to are empty.
1 year after people
Opportunity's wheels stop functioning, and is stuck in the Endeavour Crater. The debris hit other satellites, including the Hubble by debris thrown into higher orbits. The debris now start to affect GPS satellites, which are otherwise in good condition. When even the smallest debris piece hits GPS satellites, they shut down to a safe mode.
2 years after people
Opportunity shuts down due to its solar cells are covered with dust from Martian dust storms.

750 million miles from the Earth, The Cassini Probe continues to orbit Saturn. Its mission is over and NASA planned to incinerate the probe in Saturn’s atmosphere so that extremophile bacteria that may have hitched a ride on the probe would not contaminate anything, but since there is nobody to divert to probe to into Saturn the probe continues to orbit the planet.
20 years after people
The Cassini Probe crash lands on the moon Enceladus causing the extremophile bacteria that stowed away on the probe to contaminate its watery ocean.Enceladus can now sustain primative bacterial life, just as Earth can. Meanwhile the KEO satellite containg DVD's with a thousand E-mail messages still orbits the Earth. The ISS burns up when it's orbit reaches 80 x 110 km.
50 years after people
Human artificial satellites begin to collide with each other and eventually fall back into the earth's atmosphere. Without humans to control the satellites they are now slipping out of orbit and slamming into each other and knocking each other from the sky.
150 years after people
The last of the space junk has fallen down.
10,000 years after people
Abu Symbol starts to be burried under sand but it will still last for not just thousands but maybe millions. The smaller debris of such as transistors, bolts, nuts and screws satellites continue to multiply as surviving circuit boards and solar panels break up.
50,000 years after people
The KEO Satellite starts to come back to the earth, on the way it hits some other satellites. But remains unharmed, then it begins to make glints of light hoping that some one saw it. But with out anyone around it crashes and sinks into the ocean. And waits for the future.
1,000,000 years after people
The Voyager Probes are still orbiting other galaxies. However due to space debris the golden records have been damaged beyond repair. Opportunity has suffered minimal damage from Martian dust storms, but the rover is still recognizable, but it's buried under the Martian surface. Since Mars's atmosphere doesn't contain any water, corrosion doesn't occur, allowing Opportunity to outlast anything manmade on Earth.

Earth enters a new ice age.
10,000,000 Years after people,
Dragonflys will now be much more bigger than now and soon they will be the size of a meganeura.
50,000,000 years after people
The Earth begins to shape shift due to continental drift. Causing land to break up and collide with each other. The Lands begin to rotate again. Causing Alaska to collide with Siberia. The new Ice age ends.

The only evidence left of mankind are plastics, silicates, bronze, lead, gold, and our bones and teeth.
A mass extinction wipes out the mammals save for rats, shrews and tenracs. Others like snakes, roaches, mosquitoes, worms and crayfish still hod out elsewhere. Earth's temperature rises to an average of 35C.
900,000,000 after people
Aliens from Mars land in Australia, Thailand and Ohio, And began to take over, but fail shortly afterwards.
1,000,000,000 years after people
Temperature on the earth is 47 C° the plants can't live on earth, except catcuses.
1,000,500,000 years after people
Temperature on the earth is 50 C° the catcuses lives on earth.
1,300,000,000 years after people
All the animals are dead under a temperature of 70 C° save for tradigrades.

The bacterias die, leaving prokaryotes and archaeas alive.
2,000,000,000 years after people
The temperature on the earth is 140 C°. Prokaryotes die but archaeas survive. Pangea Ultima forms.
2 400,000,000 years after people
The temperature reaches 210°C. Even the Archaeas die and life is finished.
2,400,000,000 years after people
All life on Earth goes extinct.
1,000,000,000,000 years after people
The Archaea and prokaryotes bacteria on the Cassini Probe has evolved into the life that was once on Earth, transforming a barren wasteland into a lush, Eden-like paradise.
8,000,000,000,000 years after people
The bacteria from the Cassini Probe has evolved in to a new primate race like rheasus monkeys over the millennial.
10,000,000,000,000 years after people
The bacteria from the Cassini Probe has evolved in to a new human like civilization that is on a par with anent Egypt.
11,000,000,000,000 years after people
The bacteria from the Cassini Probe has evolved in to a new human like civilization that settles on the moons Titan, Io and Europa.
12,000,000,000,000 years after people
The bacteria from the Cassini Probe has evolved in to a major new human like civilization that vissets Earth, Mars and Uranus. They leave their home planet, knowing the sun is dieing and make a safe passage to the Alpha Senturi. They the flourish on their new world.

The Sun enter the red giant stage and engulfs the Mercury, Venus, Earth and Mars. Then at some point it dies and causes a super nova, witch wipes out the asteroid belt.

Super Novas start to occur all over the universe, causing the destruction of many planets.

Considering if the Earth wasn't fully consumed by the Sun, the Earth gets sucked into a black hole or poisoned by a radioactive neutron star that was once the sun instead.

The solar system is messed up likewise as far Uranus.

A little piece of matter floats around the empty space and collides with anti-matter. Matter defeats the antimatter and causes a second big bang. Thus starting the universe all over again.
