Mercury is the one least explored. UnlikeVenus,Mars, Jupiter, andSaturn, Mercury is notoriously difficult to observe from Earth. Being the innermost planet of the Solar System, it always appears too close to the Sun. While the golden time for astronomical observations is at night, Mercury sets...
Temperatures on the planet's surface (about 460°C) are in fact hotter than Mercury, even though Venus is roughly double the distance from the sun. This is higher than the melting point of many metals including bismuth and lead, which may even fall as "snow" onto the higher mountain peak...
What is the star by the moon? The light isn't actually a star, it'sthe planet Venus. Venus is the second closest planet to the sun. It was at its brightest in 2020 on April 28, and it's not at its brightest in 2021 until December 7. Why does the Moon look so big today? Why...
temperatures. The free electrons at the hotter end of the conductor gets higher thermal velocity than the colder end of the wire and these higher thermal velocity electrons diffuse to the cold end of the conductor producing a potential difference across the conductor. This effect is known as ...
In addition — failure rate notwithstanding — the planet is comparatively easy to land on and is less likely to melt our equipment than Venus or Mercury. Artist’s illustration of NASA’s InSight lander, which is scheduled to touch down on Mars on Nov. 26, 2018. (Image credit: NASA/JPL...
Venus, not to be outdone in dickishness, manages to make living on Mercury sound like sitting on the beach in Maui eating a grilled shrimp. It turns out that a vacuum is a lovely place to be compared to the exact opposite situation Venus has going—an incredibly dense atmosphere. Here’...
