Question

whats gases that surrond earth or another planet

Answer 1

The gases that surround a planet are typically found in its atmosphere. Each planet has a unique atmospheric composition based on its distance from the Sun, its mass, and other factors. Here’s a brief overview of Earth's atmosphere and the atmospheres of other planets in the solar system:

### Earth's Atmosphere
Earth's atmosphere is composed of:
- **Nitrogen (N₂)**: ~78%
- **Oxygen (O₂)**: ~21%
- **Argon (Ar)**: ~0.93%
- **Carbon Dioxide (CO₂)**: ~0.04%
- **Trace gases**: including neon, helium, methane, krypton, and hydrogen.

### Other Planets' Atmospheres

1. **Venus**:
- Mainly carbon dioxide (CO₂): ~96.5%
- Nitrogen (N₂): ~3.5%
- Trace amounts of sulfur dioxide (SO₂) and water vapor (H₂O).

2. **Mars**:
- Carbon dioxide (CO₂): ~95.3%
- Nitrogen (N₂): ~2.7%
- Argon (Ar): ~1.6%
- Oxygen (O₂): ~0.13%
- Water vapor and other trace gases.

3. **Jupiter**:
- Hydrogen (H₂): ~90%
- Helium (He): ~10%
- Methane (CH₄), ammonia (NH₃), hydrogen sulfide (H₂S), and water vapor in trace amounts.

4. **Saturn**:
- Hydrogen (H₂): ~96%
- Helium (He): ~3%
- Methane (CH₄), ammonia (NH₃), and other gases in trace amounts.

5. **Uranus**:
- Hydrogen (H₂): ~83%
- Helium (He): ~15%
- Methane (CH₄): ~2%, which gives it a blue color.

6. **Neptune**:
- Hydrogen (H₂): ~80%
- Helium (He): ~19%
- Methane (CH₄): ~1%, contributing to its blue color.

### Dwarf Planets
- **Pluto**: Has a thin atmosphere primarily composed of nitrogen (N₂), with traces of methane (CH₄) and carbon monoxide (CO).

These atmospheric compositions can affect a planet's climate, surface conditions, and potential habitability.
