What Is Venus's Revolution Period in Earth Days? People throughout the ages have appreciated the beauty of Venus, frequently the brightest object in the sky at dusk and dawn. The planet, named after the Roman goddess of art and beauty, can actually be bright enough to cast shadows on a moonless night. It appears so close to the sun because its orbital radius is smaller than the Earth's, and because it also moves faster than Earth, its orbital period is shorter. The Morning and Evening Star The fact that Venus can appear as either the morning star or the evening star prompted the ancients to give it two different names, because they thought it was two different planets. It spends about 263 days as Phosphors, the ancient Greek name for the morning star, and an equal time as Hesperus, the evening star. In between, it disappears for stretches of 8 to 50 days. These phenomena are due to the combined effect of the orbits of Venus and Earth around the sun. The sidereal per

What Are the Two Planets That Don't Get Solar or Lunar Eclipses? As Earth and the moon revolve around the sun, they periodically align with the sun in such a way that Earth moves into the moon's shadow and vice versa. Known as eclipses, these are spectacular events for observers on Earth. But they cannot occur on Mercury or Venus: Neither planet has a moon. Eclipses on the other planets in our solar system are possible but probably different than those on Earth. Mercury The first planet in the solar system, Mercury, is closer to the sun than Earth by more than half. From Mercury's surface, the sun appears three times as large as it does from Earth. If Mercury had a moon, it would have to be large enough to cover that disk for observers on the planet's surface to experience a solar eclipse. Such a moon, unless it were very close to the planet, would probably have to be larger than Mercury itself. Thirteen times every century, Earth falls into Mercury's shadow as it

What Are the Four Planets Closest to the Sun Called? The universe continues to puzzle and amaze people. Its vastness is immeasurable and its cause of creation is uncertain. Much of the information astronomers have collected about the solar system is about the four planets closest to the sun. Though no man has visited these planets, probes and telescopes have helped collect valuable information. Mercury As the closest planet to the sun, Mercury has a surface temperature that can reach 840 degrees Fahrenheit. The planet doesn't have an atmosphere to trap heat, so the nighttime temperature can plummet to minus 275 degrees Fahrenheit. Despite it's extremely hot daytime temperature, astronomers suspect ice is located deep in its craters. These craters were the result of massive meteorites striking the surface throughout Mercury's billions of years in existence. Mercury is slightly smaller than the Earth's moon and is the smallest planet in this solar system. Venus V

The Similarities and Differences Between the Sun and Moon The sun and the moon are the two most prominent celestial objects in Earth’s sky. They affect the daily lives of people in significant ways but are very different in their characteristics and effects on the solar system and the Earth. Both of these bodies have been the subjects of extensive scientific research, as well as myths and tales across the ages. Measurements of Time Both the sun and the moon serve as bases for systems of time measurement. The moon is the Earth’s only natural satellite and is the basis of the month on modern calendars. The moon takes 27.3 days to fully rotate around the earth. The sun, around which the Earth orbits, is the basis of the calendar year and day. The sun itself rotates within a period of about 25 days. How They Were Formed The moon and sun are both bright round objects in the sky. Indeed, viewed from the Earth's surface, both appear as similarly sized disks. That said, however, they are
