LD means "Lunar Distance. MAG is the visual magnitude of the asteroid on the date of closest approach.
Share Shares The Earth is in a perpetual state of change. The following list presents ten major events that the earth is predicted to experience in the coming billion years. With a mere 20km between the surface and the hot magma bubbling below, the land is being slowly thinned by tectonic movements.
Hosting a deadly array of volcanos, geysers, earthquakes and even toxic superheated water, the depression is hardly a holiday resort; but come 10 million years when all this geological activity has ceased, leaving only a dry basin, it will eventually fill up with water and form a new ocean — perfect for jet skiing in the summer.
This is of course bad news for any life on Planet Earth.
Although some species will no doubt survive, the impact will likely mark the end of the age of mammals — the current Cenozoic Era — and instead usher in a new age of complex life forms.
Who knows what sort of life will thrive on this newly purged Earth? For now though, our imagination is the only limit as to what may occur. This movement will seal up the Mediterranean sea within million years, and thrust thousands of miles of new mountain ranges into existence, much to the glee of climbers worldwide.
Australia and Antarctica will also want to be part of this new supercontinent, and shall continue their paths northwards to merge with Asia. What happens next is up for debate. It is believed that as the Atlantic ocean grows, a subduction zone will eventually form on the western border, which will drag the Atlantic sea floor down into the earth.
This will effectively reverse the direction which the Americas are travelling, and eventually force it into the eastern border of the Eurasian supercontinent in around million years time.
Either way we can look forward to the formation of a new hypercontinent: Pangaea Ultima — million years after the last, Pangaea. Following this it will likely split once more and start a new cycle of drifting and merging. Although we are bombarded by weak Gamma-ray bursts daily, a burst originating from a nearby system — within light years away — has the potential to wreak havoc for anything standing in its way.
It is believed by some that a Gamma-ray burst prompted the second largest mass extinction in history: Like all things in astronomy, however, pinning down exactly when the unlikely set of event that leads to a Gamma-ray burst directed at Earth will occur is difficult, although typical estimates place it at between 0.
But it could be as soon as a million years, should the threat from Eta Carinae be realised. By this time, all but the most resilient of life on Earth would have perished.
The oceans will have completely dried up, leaving only deserts of burning soil remaining. As time goes by and the temperature rises, Earth may go the way of Venus, and turn into toxic wasteland as it is heated to the boiling point of many poisonous metals. What remains of humanity will have had to vacate by this point to survive.
Luckily, by this point Mars will lie inside the habitable zone, and may provide a temporary haven for any remaining humans. Now with a Venus-like atmosphere, the barren Earth will feel the full force of solar radiation — making the already inhospitable land even more treacherous.
Although we cannot currently predict exactly what will occur when this happens, the best case scenario is that Mercury will simply be consumed by the Sun, or destroyed by a collision with its bigger brother Venus.
The worst case scenario? If the inner solar system remains somehow intact and undisrupted, within five billion years the orbit of Mars will cross that of Earth, creating once more a recipe for disaster.
Over time it will begin to horribly distort as both it and the Milky Way begin to merge, throwing the otherwise stable stellar arena into chaos.
Although direct collision between astronomical bodies is incredibly unlikely, there is a small chance that our Solar System may be ejected and thrown into the universal abyss. The additional force exerted on the moon by our bloated star will be enough to cause Moon to slowly come crashing back down to Earth.
Once the Moon reaches the Roche limit it will then begin to disintegrate, as the tidal force exceeds the gravity holding the satellite together.
After this it is possible that the debris will form a ring around the Earth, giving any life a pleasant skyline, until it falls back to earth again after a period of many millions of years.
If this does not occur, there is another means by which the Moon may come plunging back towards its parent. Should the Earth and Moon continue to exist in their current form, with their orbits uninterrupted, then after around 50 billion years the Earth will become tidally locked with the Moon.
This process will continue until the Moon reaches the Roche limit and disintegrates, forming a ring around the earth. Whether by the cold jaws of a rogue planet, or the smothering embrace of our dying Sun, it will no doubt be a sad moment for any surviving humans — should they even remember their birth planet.
Even then, once black holes have taken over 10 Duodecillion years from now there will be little hope for its survival.To measure radiation on airplanes, we use the same sensors we fly to the stratosphere onboard Earth to Sky Calculus cosmic ray balloons: neutron bubble chambers and X-ray/gamma-ray Geiger tubes sensitive to energies between 10 keV and 20 MeV.
You can obtain the dates of the seasons (equinoxes and solstices) and apsides (perihelion and aphelion) of the orbit of the Earth by typing the year () in .
On the other, countless catastrophic events transformed the Earth before, profoundly altering the course of evolution and leaving a trail of destruction in their wake. In this week’s listicle, we will look at 10 of the most important of these turning points in the history of our world.
Spacecraft and space exploration. To date five spacecraft (Voyager 1, Voyager 2, Pioneer 10, Pioneer 11 and New Horizons) are on trajectories which will take them out of the Solar System and into interstellar srmvision.comg an extremely unlikely collision with some object, the craft should persist indefinitely.
