The 22nd century will be a century of the Anno Domini or Common Era in accordance with the Gregorian calendar. It will be the century following the current 21st century, beginning on January 1, 2101 and ending on December 31, 2200.

Technological predictions

Social predictions

  • 2160 – Some scientists believe there are people born in 2010 who may still be alive in 2160.[9][failed verification]
  • According to the UN Population Bureau, life expectancy in 2200 will be around 100 for developed countries and the world population will be about 11 billion. However, the UN has warned that these projections could be invalidated by any change and progress in future life extension technology and discoveries, as well as changes in future birthrates.[10]

Biological predictions

  • By 2100, 12% (about 1,250) of the bird species existing at the beginning of the twenty-first century are expected to be extinct or threatened with extinction.[11]
  • By 2100, emperor penguins could be pushed to the brink of extinction due to global climate change, according to a Woods Hole Oceanographic Institution study from January 2009. The study applied mathematical models to predict how the loss of sea ice from climate warming would affect an Antarctica colony of emperor penguins, they forecast a decline of 50% by the end of the century.[12]

Calendric predictions

  • On March 14, 2100 (which will be February 29, 2100 in the Julian calendar), the difference between the Julian calendar and the Gregorian calendar reaches 14 days. Since 14 is divisible by 7, this will be the first time in history since its inception that the Gregorian calendar will have the same day of the week for each day of the month for the whole year as the Julian calendar. This will last until February 28, 2200 of the Gregorian Calendar.
  • FAT file systems theoretically support dates up to December 31, 2107 (though officially only up to December 31, 2099).
  • The Year type in MySQL supports dates up to December 31, 2155.
  • March 17, 2160 – Unless changes are made as to when Easter can be observed, this particular March 17 will fall within Holy Week for the first time since 2008 and fall on the same day (Monday) as it did in that year, likely requiring the movement of the Feast of Saint Patrick's Day to another date.[13]

Time capsules

Astronomical predictions

Solar eclipses

Lunar eclipses

  • June 9, 2123: Long-duration lunar eclipse of approximately 106.1 minutes.[28]
  • June 19, 2141: Long-duration lunar eclipse of about 106.1 minutes. This lunar eclipse is in the same Saros series (132) as the long lunar eclipse in 2123, and has an almost identical duration.[29]

Triple conjunctions

Transits and occultations

Other phenomena

  • August, 2113: First time Pluto reaches aphelion since its discovery.[37]
  • March 10, 2130: At 07:32 UTC, Sun passes through the solar system barycenter.[38]
  • 2134: Comet Halley will return to the inner solar system.[39]
  • 2135–2136: Halley's comet will be at perihelion.[39]
  • August 5, 2150: Main-belt asteroid 78 Diana (~125 km in diameter) will pass about 0.003 AU (450,000 km; 280,000 mi) from Earth threatening asteroid (29075) 1950 DA and perturb 1950 DA's long-term trajectory.[40]
  • May 19, 2161: All eight planets are predicted to be on the same side of the sun, within 69 degrees.[41]
  • 2174: The second full orbit of Neptune around the Sun since its discovery in 1846.
  • 2177: "First Plutonian anniversary" of the dwarf planet's discovery, given that Pluto's orbit is just under 248 Earth years.
  • 2182: With an estimated probability of 0.07%, Apollo asteroid 1999 RQ36 could hit the Earth.
