* 22% of Mercury's atmosphere is hydrogen. * Venus does not have pure hydrogen in its atmosphere, but does have hydrogen chloride and hydrogen fluoride. * Earth has almost no hydrogen.
* Mars does not contain any significant amount of hydrogen in its atmosphere. * Jupiter's atmosphere is roughly 90% hydrogen! * Saturn's atmosphere has even more: about 97% is hydrogen! * Uranus' atmosphere is 83% hydrogen.
* Neptune's atmosphere contains 74% hydrogen.

Which planet 's surface's is hot enough to melt lead?
the hottest planet is not the planet nearest to the sun, which is mercury. it is venus, the second nearest. it is very hot on venus because, unlike mercury, venus has an atmosphere. the atmosphere acts rather like the windows in a greenhouse, and helps to heat the surface of the planet. the temperature there is about 900 degrees, which i shot enough to melt several metals.
Who are earths neighbors?
Mars and Venus and the moon.
What element is most of the matter in the universe?
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%
A planet closet in size to earth?
Venus is a planet that is closest in size to Earth. It has similar bulk composition and gravity to Earth too.
What elements does alcohol contain?
hydrogen, carbon, oxygen
What gasses are in the atmosphere of Venus?
mercury has helium hydrogen and potassium
Is Venus is a star?
no Venus is a planet, so it hasn't hydrogen to burn, The light it shows is a reflection from the Sun. Mars is like Venus, it is also a planet.
What is water made up of Venus?
Water on Venus is made up of the same stuff as water anywhere else: hydrogen and oxygen.
Why is Jupiter darker than Venus?
For one thing, Venus is much closer to the sun than Jupiter. Also, Venus is covered with snow-white clouds where Jupiter's atmosphere has many colors that don't reflect as much light. Venus is the 3rd brightest object in the sky while Jupiter lags behind at #4.
How did Venus get where it is?
You mean why is Venus in existence? or rather why is it so hot. Venus has many volcano's which result in its mega greenhouse effect that's why its so hot. venus is here in our solar system because the Sun was formed about 4.57 billion years ago when a hydrogen molecular cloud collapsed which resulted in all of the planets we have now.
What happened to Venus' water?
Venus likely lost its water due to a combination of factors, including its proximity to the sun, which caused intense heat that evaporated water, and a lack of a magnetic field to protect it from solar wind erosion. The water molecules were broken down by sunlight into hydrogen and oxygen atoms, with the lighter hydrogen escaping into space, leaving behind a dry and inhospitable atmosphere on Venus.
Is Venus's a terrestrial or gas giant?
Venus is one of the four rocky or terrestrial planets - not a gas giant.
What is Venus's main gas?
Practically all (96.5%) of the dense atmosphere of Venus is made of carbon dioxide. The remaining gases are 3.5% nitrogen and trace amounts of sulfur dioxide, argon, water vapor, carbon monoxide, helium, neon, hydrogen chloride, and hydrogen fluoride. All of the oxygen on Venus has been bound to crustal rocks and practically all free hydrogen was lost to space. * There are clouds of sulfur dioxide and sulfuric acid "rain" that never reaches the surface. However, this could present a problem to probes passing through the atmosphere.
Which two stars contain the greatest amount of hydrogen?
The two stars that contain the greatest amount of hydrogen are dwarf stars and main-sequence stars. These stars are primarily composed of hydrogen, which fuels their fusion processes and provides them with energy.
Why is Venus a planet not a star?
Stars are mainly made of hydrogen and helium, and produce energy and light with atomic fusion at the core. Venus is made of rock and doesn't produce light, it just reflects light from the sun. Also, stars are hundreds of times bigger than Venus.
What is the leading hypothesis for Venus lack of water?
The leading hypothesis for Venus's lack of water is that it experienced a runaway greenhouse effect early in its history. This process caused high temperatures to evaporate any existing water on the surface, with the vapor then being broken down by ultraviolet radiation and the hydrogen escaping into space.
Which of the eight planets contain hydrogen?
All of the planets (major, dwarf and minor) - and everything else in the universe - contains hydrogen, which is the most common element in the universe. Earth, of course, contains megatons of hydrogen in the form of H₂0 or "water". The clouds of Venus contain substantial quantities of H₂SO₄, or sulfuric acid. The gas giant planets such as Jupiter and Neptune contain ammonia, which is also made of hydrogen.
