Distance from the Sun (for star systems not our own, distance from the primary star(s)) the closer to a star the more energy reaches the planet.
Atmospheric composition - how much energy gets to the surface and how much is trapped in.
Terrestrial composition; what the solid stuff is made of and how it reacts with stellar/solar energies. Some things reflect light back, others absorb the energy and radiate it back as heat.
Also, for planets not around the Sun, the size and energy output (heat) of the star(s) would be factored in. :P
the first encounter with another planet. it was a spacecraft sent by NASA to venus. it measured venus' temperature and is now thought to be orbiting the sun.
Mariner 2 was a NASA spacecraft launched in 1962 with the primary purpose of conducting a flyby of Venus. It aimed to gather data about the planet’s atmosphere, surface temperature, and radiation levels. The mission successfully provided the first close-up observations of another planet, revealing that Venus had a high surface temperature and a dense atmosphere composed mostly of carbon dioxide. Mariner 2 marked a significant milestone in planetary exploration and contributed to our understanding of the solar system.
As of now, Voyager 2 has not found Planet X. The existence of Planet X, also known as Planet Nine, is still a topic of ongoing research and debate among astronomers. It has not been directly observed or confirmed by any spacecraft like Voyager 2.
A planet's orbital radius directly affects its orbital period through Kepler's third law of planetary motion. The farther a planet is from the star it orbits, the longer its orbital period will be, assuming all other factors remain constant. This relationship is expressed mathematically as T^2 ∝ r^3, where T is the orbital period and r is the orbital radius.
In "Spectrobes 2: Beyond the Portals," you can find the Grillpod Fossil on the planet Kollin.
In Planet Earth 2, the unique characteristics of baby iguanas are showcased through their remarkable agility, speed, and ability to evade predators such as snakes with their quick reflexes and camouflage.
Temperature and Precipitation.
It 1) moderates it (the swings from hot to cold are minimized), 2) it warms the planet (CO2 & water vapor (etc) trap infrared re-radiation (at night).
The strength of the planet's gravitational field and exposure to solar wind.
Colour, density, mass
temperature and mostiure
the temperature and the salinity
Mariner 2 flew past the planet Venus in 1962, becoming the first spacecraft to successfully encounter another planet. It provided valuable information about Venus's atmosphere and surface temperature.
MarsYou have listed three features of the planet; rocky surface, hot temperature, and 2 moons. While Mars is a terrestrial planet (has a rocky surface) and has 2 moons (Phobos and Deimos), you're wrong on the last feature, in which you have written that Mars has hot temperature conditions. This is wrong, because the temperature on Mars is usually well below zero.
