At some point in the next few hundred thousand years, the Wolf–Rayet star WR 104 may explode in a supernova. There is a small chance that WR 104 is spinning fast enough to produce a gamma-ray burst (GRB), and an even smaller chance that such a GRB could pose a threat to life on Earth.

It is estimated that every 100 million years, Earth will be hit by an asteroid about 10–15 km in diameter, comparable in size to the one that triggered the K–Pg extinction which killed dinosaurs 66 million years ago. [209] 500–600 million Anne Minard
Visual representation of the Logarithmic timeline in the scale of the universe. This timeline shows the whole history of the universe, the Earth, and mankind in one table. . Each row is defined in years ago, that is, years before the present date, with the earliest times at the top of the ch
1000 was a leap year starting on Monday of the Julian calendar, the 1000th year of the Common Era (CE) and Anno Domini (AD) designations, the 1000th and last year of the 1st millennium, the 100th and last year of the 10th century, and the 1st year of the 1000s decade.
These timelines of world history detail recorded events since the creation of writing roughly 5000 years ago to the present day.

In 10,000 years, the post-glacial rebound of the Baltic Sea will have reduced the depth by about 90 m (300 ft). The Hudson Bay will decrease in depth by 100 m over the same period. [38] After 100,000 years, the island of Hawaii will have shifted about 9 km (5.6 mi) to the northwest. The planet may be entering another glacial period by this time.
The first millennium of the anno Domini or Common Era was a millennium spanning the years 1 to 1000 (1st to 10th centuries; in astronomy: JD 1 721 425.5 – 2 086 667.5 [1]). The world population rose more slowly than during the preceding millennium, from about 200 million in the year 1 to about 300 million in the year 1000. [2]
The date used as the end of the ancient era is arbitrary. The transition period from Classical Antiquity to the Early Middle Ages is known as Late Antiquity.Late Antiquity is a periodization used by historians to describe the transitional centuries from Classical Antiquity to the Middle Ages, in both mainland Europe and the Mediterranean world: generally from the end of the Roman Empire's ...
