Does a planet need to have at least one natural satellite to be considered a planet?
Of the eight planets in our solar system, the first two (Mercury and Venus) have no natural satellites. The dwarf planets Pluto and Eris have six moons between them. There is no relationship between the number of moons an object has and whether or not it is a planet. Planets may have no moons, while objects that are not planets may have multiple moons. In general, the larger the planet, the more moons it tends to have.
Which 3 planets do not possess satellites?
Neither Mercury nor Venus have natural satellites. Earth has one natural satellite and several thousand artificial ones. All of the other planets have at least two (Mars) or more.
Which two planets do not have their own satellite?
Mercury and Venus both lack natural satellites. Mars has two small ones. Jupiter and Saturn each have more than 60, with Ganymede and Titan both being larger than Mercury.
What is the difference between a moon and a satellite?
A moon is one kind of satellite, a smaller body that orbits a much larger body.The term "moon" refers to a natural satellite of substantial size.However in common usage "satellite" has been used more and more to mean an artificial (man-made) object that orbits a planet, natural satellite, the sun, an asteroid, or another natural body..
How many known natural satellite does Jupiter have?
Currently there are 63, the most of all eight planets in our solar system. More could be discovered in the future though.
What planet has only 1 satellite?
So far, we know that Mercury and Venus do not have natural satellites, while the Earth, Mars, Jupiter, Saturn Uranus and Neptune do have natural moons. If we include artificial (man-made) satellites, then Venus has some as well. Of the extra-solar planets (planets that orbit other stars) we do not yet know of any moons. But it would be impossible for our current technology to detect the moons of planets so far away. Give us a few more years, and we may be able to answer those questions.
More massive planets have more satellites why?
More massive planets have more gravitational pull. If a satellite were to pass by Earth and Jupiter at the same distance from each planet, the satellite would be more attracted to start orbiting Jupiter because of its pull. The more massive a planet is the more likely it is to get a satellite to orbit it.
What is the difference between a planet and a natural satellite?
A planet is an object that orbits a star, has enough gravity to make itself mostly round, and has cleared other objects out of its orbit. A satellite is an object that orbits another object that is itself orbiting a star. The object may be a planet, dwarf planet, asteroid, or comet.
Is the moon a small planet?
You could describe it as that, but it would more properly be described as a natural satellite of Earth. Most moons are small planets, but are commonly referred to as satellites.
Does Jupiter have the biggest natural satellite?
Of the eight planets, Jupiter has the most known satellites (63+). However, Saturn may have more than its known count of 60, as Saturn is much farther away and its moons more difficult to observe.
A short definition for natural selection?
Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this leads to the evolution of a population with traits that are better suited to their environment.
The largest natural satellite in your solar system belongs to which planet?
Ganymede, a satellite [of Jupiter] is the largest moon in the solar system. It is actually bigger than Mercury.See related link for more information.
