There are probably a very great number of planets in our galaxy with no atmosphere. Of the 400+ planets that we know of, we can only determine the presence or absence of an atmosphere for the 8 planets in THIS solar system; our technology is not yet good enough to study atmospheres from several light-years distance.
Of the planets of this solar system, we are fairly sure that Mercury has no atmosphere to speak of. Of the other seven, we know that Mars has a very thin atmosphere, but enough to use a parachute in. If we include dwarf planets, we can say with some certainty that Ceres doesn't have enough mass to retain an atmosphere, and Pluto's atmosphere is almost certainly all frozen by now.
What else can I help you with?
Which planet has the least amount of craters due to is protective atmosphere?
Venus has a very dense atmosphere, which helps burn up many meteors it pulls in. This lets the planet have many less craters than others. Additionally, the gas giants don't have any known craters, since they are made of mostly gas.
What planet has the most visible craters?
Mercury is the planet with the most visible craters in our solar system. Its surface is heavily pocked with impact craters due to its lack of atmosphere to protect it from incoming space debris.
How could the craters on venus be described?
The craters on Venus vary in size and shape, with some being large and circular while others are more irregular. Due to the planet's thick atmosphere, many craters appear eroded or partially filled in by volcanic activity. Overall, Venus's craters can provide important insights into the history of impacts and geological processes on the planet.
What planet is covered with craters made by meteorites?
The planet covered with craters made by meteorites is Mercury. Its lack of an atmosphere to protect it from impacts has allowed billions of years of meteorite bombardment to create a heavily cratered surface.
Why are there craters on Jupiter?
Craters on Jupiter are typically caused by impacts from asteroids or comets. Jupiter's strong gravitational pull can attract these objects, leading to collisions with its surface. The planet's thick atmosphere can also cause meteors to explode before impact, creating visible scars on its surface.
Which planet has the least amount of craters due to is protective atmosphere?
Venus has a very dense atmosphere, which helps burn up many meteors it pulls in. This lets the planet have many less craters than others. Additionally, the gas giants don't have any known craters, since they are made of mostly gas.
Was there any craters on the moon?
Yes, there are craters on the Moon. Any planet with a solid surface and not too much of an atmosphere will have craters.
What planet is full of impact craters and and no atmosphere?
I think it is Mercury.
What is the relationship between the number of craters and the thickness of a planet's atmosphere?
The thinner the atmosphere, the more craters the planet has. Planets with thicker atmospheres burn up most asteroids before they hit the ground.
How would you tell that a planet or a moon had no atmosphere just by looking at the surface?
If there are lots of craters, it means there is no significant atmosphere. The reason is that any craters will be eroded eventually, by the presence of an atmosphere.
True or false craters on mercury surface are eroded only very slow this planet has a sulfuric acid atmosphere?
False. Craters are not eroded on Mercury, which has no atmosphere.
What has many craters no atmosphere?
Mercury.
What planet has the most visible craters?
Mercury is the planet with the most visible craters in our solar system. Its surface is heavily pocked with impact craters due to its lack of atmosphere to protect it from incoming space debris.
Does the planet Venus' have craters?
Venus has about 1,000 young craters, the biggest of which is Crater Mead, about 170 mile across. Oddly, there is no evidence on Venus of old craters like we see on the moon, Earth, and Mars. Somehow these old craters were smoothed over on Venus . . . by lava flow?? By high winds??
Which terrestrial planet has no craters?
There is no terrestrial planet without craters.
What is the surface of planet mercury covered with?
The surface of Mercury is covered with craters, plains, and ridges. It also has volcanic plains and impact craters formed by collisions with asteroids and comets. The planet's surface is rocky and heavily cratered due to its lack of atmosphere to protect it from impacts.
Is Venus' made of dust?
Venus is a rocky planet with a very thick atmosphere due to greenhouse gasses. Many volcanos and craters also are abundnt on Venus.
