Venus is known as the Earth’s “twin” because the planets are so like each other in size. The diameter(直径)of Venus is about 7, 520 miles(12, 100 km), about 400 miles(644 km)smaller than that of the earth. No other planet comes closer to the earth than Venus. At its nearest...

Our own Sun is an example of an average star. It has a diameter of 1.4 million kilometers… today. But when our Sun nears the end of its life, it will bloat up as a red giant, and grow to 300 times its original size. This will consume the orbits of the inner planets: Mercury, ...
These are the coolest, least-massive stars, with masses ranging from about 0.08 to 0.6 solar masses, according to the Space Telescope Science Institute in Baltimore. TRAPPIST-1 is one of the smallest known M dwarfs, with a diameter of 52,300 miles (84,180 kilometers — just 12% of the...
Known scientifically as JA 1989, this Apollo-class astroid is quite large with a diameter of 1.8 kilometers (1.2 miles). That is basically the length of Green River Road between Morgan Avenue and the Lloyd Expressway here in Evansville. ...
Venus: 2,605 Wm⁻² (191%) Earth: 1,361 Wm⁻² (100%) Mars: 589 Wm⁻² (43%) Jupiter: 50 Wm⁻² (3.7%) Saturn: 15 Wm⁻² (1.1%) Uranus: 3.7 Wm⁻² (0.3%) Neptune: 1.5 Wm⁻² (0.1%) Video: The Apparent Size of the Sun from other planets ...
Two other small planets orbiting stars smaller and cooler than our sun recently were confirmed on the very edges of the habitable zone, with orbits more closely resembling those of Venus and Mars. "This is a major milestone on the road to finding Earth's twin," said Douglas Hudgins, ...
By contrast, the Chelyabinsk meteor that exploded over Russia in 2013 started out as an asteroid bigger than asteroid 2016 RB1, with a diameter of about 56 feet (17 m). While falling debris from that explosion injured more than 1,000 people, no one died during this dangerously close ...
Placing three well-known asteroids (Eros, Mathilde, and Gaspra) side by side provides a dramatic illustration of their irregular shapes. miles in diameter, somewhat larger than the state of Pennsylvania. Vesta is the third largest of the asteroids, with a diameter of 310 miles. Fourth c...
