A "Gas Giant" planet.
All the planets are large bodies that orbit the sun.
Venus. Carl Sagan proposed back in 1993 that we should strike Venus with large asteroids, in an attempt to eject the inhospitable atmosphere away from the planet. With current technology, such as rockets and nuclear weapons, this can be done.
all parts of the planet pulled each other toward the center of the mass by gravity
The large size of the terrestrial planet
The planet is Earth
A "Gas Giant" planet.
a planet is a large bit of rock floating in are atmosphere
Jupiter
The planet Earth has a sufficiently large mass, and correspondingly large gravitational field, to enable it to hold on to a large atmosphere.
All the planets are large bodies that orbit the sun.
Mercury, the smallest planet that is also closest to the sun. It is due to these reasons that it has no atmosphere, so the surface is a near vacuum. There are trace gases about, but not in large enough amounts to call a real atmosphere.
The greatest concentration of nitrogen on the Earth is found in its atmosphere. The atmosphere is approximately 78 percent nitrogen.
That is commonly called a gas giant.
Venus. Carl Sagan proposed back in 1993 that we should strike Venus with large asteroids, in an attempt to eject the inhospitable atmosphere away from the planet. With current technology, such as rockets and nuclear weapons, this can be done.

The atmosphere of the Earth is almost 20% oxygen.it has big dicks and it is very big it has thousands of dicks
