2 days ago · Pluto (bottom left) compared in size to the Earth and the Moon. Pluto's diameter is 2 376.6 ± 3.2 km and its mass is (1.303 ± 0.003) × 10 22 kg, 17.7% that of the Moon (0.22% that of Earth). Its surface area is 1.774 443 × 10 7 km 2, or just slightly bigger than Russia or Antarctica.
2 days ago · Africa is the world's second largest and second-most populous continent after Asia. At about 30.3 million km 2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth 's land area and 6% of its total surface area. [7] With 1.4 billion people [1] [2] as of 2021, it accounts for about 18% of the world's human population.
1 day ago · Image of the Sun's cell-like surface structures. The visible surface of the Sun, the photosphere, is the layer below which the Sun becomes opaque to visible light. Photons produced in this layer escape the Sun through the transparent solar atmosphere above it and become solar radiation, sunlight.
1 day ago · While the surface conditions of Venus are inhospitable, the atmospheric pressure, temperature, and solar and cosmic radiation 50 km above the surface are similar to those at Earth's surface.
2 days ago · The surface of Mercury is heavily cratered, as a result of countless impact events that have accumulated over billions of years. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi) and one-third the diameter of the planet (4,880 km or 3,030 mi).
