Often called Earth's sister planet,Venusis the closest in size, with a mass of more than 80 percent that of our planet and a diameter of only a few miles less. It is also the closest planet to our own in terms of location. But despite these similarities, the two planets have vastly ...
The Hubble Space Telescope is deployed from the cargo bay of the space shuttle Have you ever stared at the night sky and wondered what the universe looks like up close? Even if you're lucky enough to have access to a ground-based telescope, whose clarity depends on atmospheric factors ...
Sixteen asteroids have diameters of 240 kilometers or larger, the largest of which is Ceres, which has a diameter of about 1,000 kilometers. Are all asteroids in our solar system in the main belt, or are there other bodies that share the space between Mars and Jupiter? And what about ...

and the 2024 eclipse begins. At such times, the Moon is directly between the Sun and Earth, and it casts its shadow on our planet.Because the Sun is large, the Moon’s shadow has two parts. If you’re under the outer, lighter shadow — called the penumbra — you will see a ...
To get the same effect in the ancient world, astrolabe makers cut away large portions of the metal, leaving behind a skeletal-like ring. The rete was marked with a number of stars and several important constellations. As it rotated around a central pin (the north celestial pole), the ...
Venus [Sun’s angular diameter: 0.7°] The Sun’s angular diameter in Venus’s sky is about 0.7°. The Sun cannot be seen from Venus’ surface because of its dense, cloudy atmosphere, but this is how our Sun would look like from Venus’ orbit. This image is an artist’s concept of...
Paint the planets. Using the toothpick to hold the planets and the paintbrush to apply color, paint the planets with their appropriate colors. Mercury is gray; Venus, light yellow; Earth, blue and green; Mars, red; Jupiter, bands of orange and white; Saturn, light yellow; Saturn's rings...
What is Earth's diameter in miles? How big is the asteroid belt compared to Earth? How large is the Jovian magnetosphere? How hard is meteorite? How large is the Diamond synchrotron? How much of Earth's atmosphere is made up of nitrogen and oxygen?
Unlike transits of the sun involving the planet Mercury, those of Venus are readily visible with the unaided eye; the planet appears as a distinct — albeit tiny — black spot with a diameter just 1/32 that of the sun. This size is large enough to readily perceive with the naked eye. ...
