Can inferior planets undergo retrograde motion?
The two inner planets Mercury and Venus move in retrograde motion (east to west along the ecliptic) between their time of greatest distance from the Sun (elongation) to the east as an evening star and their greatest elongation west as a morning star.
What planets are visible in November 2008?
Venus and Jupiter will be the only planets visible in the evening sky in November. During November the gap between the two planets will diminish until they are little over 2 degrees apart at the end of the month. Saturn will move a little higher into the morning sky, rising 3 hours before the Sun by November 30. Venus and Jupiter will be the only planets visible in the evening sky in November. During November the gap between the two planets will diminish until they are little over 2 degrees apart at the end of the month. Saturn will move a little higher into the morning sky, rising 3 hours before the Sun by November 30.
Are there any planets located near the star algol?
There are no known planets located near the star Algol, which is a binary star system consisting of two stars. The distance between the two stars is relatively close, making it difficult for planets to stably orbit either of the stars.
Why did early astronomers think that mercury was two separate planets?
Early astronomers observed that Mercury had two distinct elongated appearances: as a morning star and as an evening star. They mistakenly believed these were two separate planets when, in fact, it was due to Mercury's proximity to the Sun causing it to be visible at certain times from Earth.
What crawls in the morning walks on 2 in the afternoon and 3 in the evening?
The answer to this riddle is a person—they crawl on all fours as a baby in the morning, walk on two legs during adulthood in the afternoon, and may need a cane in old age in the evening, representing three legs.
Which planet was thought as two planets?
Venus was once thought to be two separate planets because of its phases when observed from Earth. This led to the misconception that there were two distinct bodies - "Morning Star" when it appeared in the morning and "Evening Star" when it appeared in the evening.
What planet was once thought to be two planets?
Both Mercury and Venus have been known as the "morning star" or "evening star" in some form for various cultures and civilizations. Sometimes, these evening and morning appearances were thought to represent different "stars." (Of course, they are not stars at all and are rather the two planets closest to the Sun.) In ancient Greece, Mercury was called Apollo when it appeared as a morning star with sunrise and Hermes (the Greek equivalent of the Roman god Mercury) when it appeared as an evening star near sunset. Venus was also known to ancient civilizations both as the "morning star" and as the "evening star". The Greeks thought of the two as separate stars, Phosphoros and Hesperos, until the sixth century BC. The Romans designated the morning aspect of Venus as Lucifer (meaning Light-Bringer) and the evening aspect as Vesper. Venus is dramatic in the morning and evening sky while Mercury is smaller, dimmer and hard to see. (Most people have never seen Mercury and everyone has seen Venus whether they know it or not.) As a consequence, references to Venus are more common when the term morning star or evening star are made. (It is also true that sometimes any star that is the first visible start of the morning or evening is given such a name for that particular day.)
Is it cheaper to set heating for two hours morning and evening or to set all day morning to evening?
Certainly it is more cheaper to set heating for two hours morning and evening rather than to set it for all day long.
What are the two largest stars next to the moon?
The two brightest stars near the Moon are usually the planets Venus and Jupiter. Venus is often referred to as the "evening star" when it is visible after sunset, and Jupiter is the largest planet in our solar system.
What two stars are visible in the west at Red Deer this evening?
They were not stars, but were the two planets, Venus and Jupiter. They appear at this time to be quite close together in the sky, but over the next weeks they will seem to drift apart, night by night. This is because of their different orbits and the millions of miles between them.
What are two ways that planets are different from stars?
1) Although planets can be composed primarily of rock or gas, only stars are objects made of gas that are massive enough to support a nuclear fusion reaction. 2) Although planets and stars can orbit stars (as in binary systems), stars never orbit planets.
Can inferior planets undergo retrograde motion?
The two inner planets Mercury and Venus move in retrograde motion (east to west along the ecliptic) between their time of greatest distance from the Sun (elongation) to the east as an evening star and their greatest elongation west as a morning star.

Compare the distance between two stars and the distance between two planets?
The distance between two stars is typically much greater than the distance between two planets. Stars are usually light-years apart, while planets in the same star system are typically within a few astronomical units of each other.
Are there any planets located near the star algol?
There are no known planets located near the star Algol, which is a binary star system consisting of two stars. The distance between the two stars is relatively close, making it difficult for planets to stably orbit either of the stars.
Are stars visible in the daytime?
Since the visible planets as a class are the brightest things in the sky (after the Sun and Moon), the first object to appear in the evening twilight sky ... referred to historically as the "Evening Star" ... is typically a planet. It can be Mercury, Venus, Mars, Jupiter, or Saturn. However, Venus is usually referred to as the Morning and Evening star.
What goes on four feet in the morning two feet at noon and three feet in the evening?
The answer to this riddle is a man. In the morning of his life he crawls or goes on four feet, in the afternoon of his life he walks on two feet, and in the evening of his life he uses a cane and goes on three feet.
