Density: 5.43 g/cm³

Composition: The specifics of mercury aren’t known, but is estimated 70% metals and 30% silicates.

Diameter: 3,032 miles (4,879 km)

Hypothesis: If a bomb was dropped on Mercury, the planet would take it like it has all of its other impacts in the past. A crater would be formed, but since mercury is small, and has no atmosphere, the bomb wouldn’t have a mushroom cloud. The bomb could also scatter parts of the planets crust and throw it into the planets orbit creating maybe a very small moon, or small thin ring.

Density: 5.24 g/cm³

Composition: Venus is made up of a central iron core and a rocky mantle, similar to the composition of Earth. Its atmosphere is mainly made up of carbon dioxide (96%) and nitrogen (3%), with small amounts of other gases.

Diameter: 7,520 miles (12,104 km)

Mass: 5.972E24 kg

Density: 5.51 g/cm³

Composition: Earth's crust is made up of several elements: iron, 32 percent; oxygen, 30 percent; silicon, 15 percent; magnesium, 14 percent; sulfur, 3 percent; nickel, 2 percent; and trace amounts of calcium, aluminum and other elements.

Diameter: 7, miles

Hypothesis: If one of these were detonated on Earth, it would destroy its surroundings and create a massive crater, but wouldn’t destroy life. It would take 15.5 of these to destroy all life on Earth.

Mass: 639E21 kg

Density: 3.93 g/cm³

Composition: silicon, oxygen, iron, magnesium, aluminum, calcium, and potassium.

Diameter: 4,212 miles

Hypothesis: If a bomb was to hit Mars it would be similar to Earth, a crater would appear, the atmosphere would be disturbed, and radiation would surround the area where the bomb detonated.

Mass: 1.898E27 kg

Density: 1.33 g/cm³

Composition: 88–92% hydrogen and 8–12% helium

Diameter: 86,881 miles

Hypothesis: Jupiter’s gases are that of the sun, but jupiter isn’t big enough to turn into a sun, and also couldn’t catch fire because the gases can’t burn without oxygen. What would likely happen is that a small amount of gas would escape jupiter forming more bodies, and would also possibly create a storm on jupiter that could grow to be a second red spot.

Mass: 568.3E24 kg

Density: 687.00 kg/m³

Composition: hydrogen, helium, frozen ammonia, frozen methane, and frozen water (Ice).

Diameter: 72,367 miles

Hypothesis: Some materials could leave the planet and collide with the rings causing the rings to lose shape or change shape and composition.

Mass: 86.81E24 kg

Density: 1.27 g/cm³

Composition: 83% hydrogen, 15% helium and 2% methane

Diameter: 31,518 miles

Hypothesis: Nothing would happen except for the possibility of creating a storm on the surface of the planet like the one on Jupiter.

Mass: 102.4E24 kg

Density: 1.64 g/cm³

Composition: hydrogen and helium, with some methane

Diameter: 30,599 miles

Hypothesis: Nothing would happen except for the possibility of creating a storm on the surface of the planet like hypothesised would happen to uranus.

Mass: 1.30900 × 1022 kilograms

Density: 2.03 g/cm³

Composition: Pluto's composition is unknown, but its density (about 2 gm/cm3) indicates that it is probably a mixture of 70% rock and 30% water ice much like Triton. The bright areas of the surface seem to be covered with ices of nitrogen with smaller amounts of (solid) methane, ethane and carbon monoxide.

Diameter: 1,471 miles (2,368 km)

Hypothesis: If the bomb landed on Pluto it would most likely destroy just a small chunk of the planet and that really is it.
