The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 10 9 years ± 1%). This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed.
Insectivorous bats may eat over 120 percent of their body weight per day, while frugivorous bats may eat over twice their weight. They can travel significant distances each night, exceptionally as much as 38.5 km (24 mi) in the spotted bat ( Euderma maculatum ), in search of food. [147]
Its entire body is densely furred, including its uropatagium. It is a medium-sized member of its genus, weighing 7–13 g (0.25–0.46 oz) and measuring 109 mm (4.3 in) from head to tail. Its ears are short and rounded, with triangular tragi. Its wings are long and pointed. Its tail is long, at 52.7 mm (2.07 in) long.
Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
Megabats take their name from their larger weight and size; the largest, the great flying fox (Pteropus neohibernicus), weighs up to 1.6 kg (3.5 lb); some members of Acerodon and Pteropus have wingspans reaching up to 1.7 m (5.6 ft).
NASA just announced that they've found 219 potential planets, and of those, 10 are close to the size of Earth and could possibly sustain life. NASA finds evidence of 10 new Earth-size planets that ...
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
