The orbital path of the ISS travels over the regions of Earth that contain more than 90 percent of the Earth's population, giving scientists a unique view of our planet. [39] In addition to the view, the ISS also provides better spatial resolution and variable lighting conditions as compared with other satellites used for Earth observation. [39]
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent ...

Population estimates for world regions based on Maddison (2007), [29] in millions. The row showing total world population includes the average growth rate per year over the ...
In the first scenario, where the world is expected to continue to develop economically in a similar way to the last 50 years, researchers estimate the global population could peak at 8.6 in 2050 ...
The world’s population is expected to grow by more than 2 billion people in the next decades and peak in the 2080s at around 10.3 billion, a major shift from a decade ago, a new report by the ...
In 1991, Kessler published "Collisional cascading: The limits of population growth in low Earth orbit" [14] with the best data then available. Citing the USAF conclusions about creation of debris, he wrote that although almost all debris objects (such as paint flecks) were lightweight, most of its mass was in debris about 1 kg (2 lb 3 oz) or ...
By RYAN GORMAN Earth could be teeming with more than 12 billion humans by the end of the century, a new study has revealed. The world's human population currently stands at about 7.5 billion. A ...
Earth's co-orbital asteroids population consists of quasi-satellites, objects with a horseshoe orbit and trojans. There are at least seven quasi-satellites, including 469219 Kamoʻoalewa, ranging in diameter from 10 m to 5000 m.
