Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. Sao Kim là hành tinh thứ hai tính từ mặt trời và có nhiệt độ duy trì ở mức…

The Earth’s interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. … Bên trong Trái đất bao gồm bốn lớp, ba lớp chất rắn và…

When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C). Khi ánh sáng mặt trời chiếu vào bề mặt mặt trăng, nhiệt độ có thể lên tới 260 độ F (127 độ C). Khi…

Apollo 10, the fastest manned spacecraft, traveled 24,790 mph. At that speed, it would take about 156 days to reach the Sun. The sun is not too far, only 93,000,000 miles away. So with a rocket traveling at 20,000 miles per hour, it will take only 193.75 days. Apollo 10, tàu vũ trụ có người…

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. … This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.

The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang. Toàn bộ Dải…

Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). But even at this speed, it takes us about 230 million years to make one complete orbit around the Milky Way. The Sun rotates as it orbits the center of the Milky Way. Hệ mặt trời của…

Earth revolves around the sun in 365 days, 5 hours, 59 minutes and 16 seconds. The time a planet takes to revolve around the sun is called a year. Trái đất quay quanh mặt trời trong 365 ngày, 5 giờ, 59 phút và 16 giây. Thời gian trái đất quay quanh mặt trời được gọi…
