According to the IAU's definition of a planet:
"A planet is a celestial body that: (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood round its orbit."
This specific definition doesn't specify that a planet needs to have satellites in orbit around it. So Mercury and Venus are planets though they don't have moons.
What else can I help you with?
What is the order from the sun to Venus?
the first planet out of the nine planets and the closest planet to the sun is mercury.First planet.
Which planet has fewer satellites?
In our Solar System, Planet Mercury and Planet Venus have no (0) satellites at all. No satellites orbit them. But if you are talking about planets with satellites and with the fewest moons, it is the Earth. Earth has only one natural satellite, THE MOON.
Which planets with only one moons?
In OUR solar system, Earth is the only planet with one moon. Mercury and Venus don't have any moons, Mars has two, and the rest of the planets have more. Jupiter is in the lead, with more than 60 moons, and more still being discovered .
Does Venus have any satellites?
No. Venus has no natural satellites (moons). Neither does Mercury.
Which planet is not a gas planet?
Mercury, Venus, Earth, Mars and Pluto are not gaseous. Pluto is sometimes not regarded as a planet. Jupiter, Saturn, Uranus and Neptune are gaseous, although the latter two may have a solid core of frozen gas.
Is Venus the second closest to Earth?
Yes because I searched it and it was part of earth but had been separated and its still the closest planet to earth.
Does Venus have any moons and what are the names?
No, Venus has no moons. Either none were formed during its history as a planet, or any that may have been formed could have been pulled from orbit by the gravity of the Sun and other planets. Mercury, even closer to the Sun, also has no moons. Any moon in too close an orbit could be destroyed by tidal forces (the Roche Limit). The tidal forces on a Venusian moon would differ from those on Earth's Moon. Rotationally speaking, Venus is practically standing still, and would exert a slowing force on any moons, no matter which direction they orbited in.
How many planets in your solar system have moons?
There are 8 planets in our solar system that have moons. These planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Each of these planets has one or more moons orbiting around them.
What are the planets in order from sun to the last planet?
Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and (if you still consider it a planet) Pluto.
What is the third plant from the sun?
list of planets(closest to the sun first) Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
Is mercury gaseous or terrestrail?
It is terrestrial. The terrestrial plants are: Mercury Venus Earth Mars Pluto (if you still pretend it's planet. I do!) The gaseous are: Saturn Jupiter Neptune Uranus
Does Saturn have 24 moons?
The planet Saturn has 53 named moons (not only 23 moons), and another nine which are still being studied.Many of the moons are very small: 33 are less than 10 km in diameter and 13 moons are less than 50 km.Many of the moons are named after Titans, giants, or minor Greek or Roman gods.Some of Saturn's moons are very large; the moon Titan is bigger than the planet Mercury.
