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 ...
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 ...
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 ...

These questions were answered in 2006 when scientific models suggested that Venus used to have a moon. The planet didn't escape the solar system debris and was actually hit twice. In the first barrage, which happened early in its life, the planet was hit by matter large enough to form a...
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 ...
How big is the large Magellanic cloud? How big are objects in the Oort cloud? What is the angular size of the Sun from mars? How much smaller is Venus than the sun? How big is the Kepler Space Telescope? How big is the Whirlpool Galaxy? How big is Comet Kohoutek? How big is the...
A telescope's ability to collect light is directly related to the diameter of the lens or mirror -- the aperture -- that is used to gather light. Generally, the larger the aperture, the more light the telescope collects and brings to focus, and the brighter the final image. The tele...
Despite that - some observers suggest using a full aperture filter even in large instruments. This allows to reveal finer solar detail (such as granulation) during steadier seeing, especially at the morning (or winter) when the ground is cold. I observed once a Venus transit with a 8" Newto...
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...
