Venus: Hottest Planet
Venus: Hottest Planet
Venus is the hottest planet in our solar system. It has a thick atmosphere that traps heat, making it extremely hot.
Venus's Surface
Venus's Surface
Though similar in size and composition to Earth, Venus has a very different surface. Most of it is covered with volcanic plains, lowlands, and highlands.
Venus's Atmosphere
Venus's Atmosphere
Venus's thick atmosphere is composed mainly of carbon dioxide, which traps heat and contributes to its extreme temperatures.

Study Notes
Venus Overview
- Venus is the second planet from the Sun.
- Venus's surface temperature is 465° degrees Celsius.
- Venus is approximately 40 million kilometers from Earth.
- A one-way trip to Venus would take around 4 months; a round trip, 8 months.
Venus Characteristics
- Venus's surface is mostly gentle plains with large lowlands and highlands (roughly the size of Australia and South America).
- It has mountains, volcanoes, and extensive old lava flows.
Past Missions to Venus
- Magellan: NASA Venus Radar Mapping Mission (1989-1994)
- Pioneer Venus: NASA Orbiter/Probes to Venus (1978-1992)
- Venera: Soviet Venus Missions (1961-1983)
- Mariner 10: NASA Mission to Venus and Mercury (1973-1975)
Proposed Venus Mission
- Objective: Send a rover to Venus to collect surface samples and compare them with Earth samples to discover potential connections between the two planets.
- Landing site: Venus's surface.
- Sample comparison aims: Exploring potential similarities and differences between the two planets, especially given their similar size and composition.
Mission Requirements: Ship
- Heat resistance: The spacecraft must withstand Venus's extreme heat.
- Cloud penetration: The spacecraft must be able to traverse the thick Venusian atmosphere.
- Fuel type: Liquid hydrogen and rocket-grade kerosene.
Mission Requirements: Rover
- Terrain navigation: The rover needs to navigate the volcanic terrain of Venus.
Required Technology
- Camera: For visual data.
- Drill: To collect surface samples.
- Infrared camera: To examine lava flows.
- Radioisotope power system: For power.
- Humidity sensors: To measure atmospheric conditions.
- Small arm (or manipulator): For handling samples and tools.
Venus's Physical Properties
- Gravity: 91% of Earth's gravity.
- Temperature: Hottest planet in our solar system.
- Type: A terrestrial (rocky) planet.
- Atmosphere: Thick atmosphere, trapping heat and leading to extreme temperatures.
- Rotation: Rotates in the opposite direction to Earth and most other planets.
