I am back again with an interesting topic, as i do every day.In our previous blog we learn about life on mars. Today we shall understand about "Mars Orbit"
Mars orbits about one and half times farther from the Sun than Earth does, which is the main reason it's so much colder. The orbit of Mars is also noticeably more elliptical than Earth's. This means the amount of solar heat received during the day at any given point on the planet's surface varies widely between when Mars is closest to the Sun (perihelion) and when it's farthest away (aphelion). Big swings in temperature are the result.
Although the yearly average temperature over the whole surface is about -55°C (-67°F), the temperature ranges from as low as -133°C (-207°F) at the winter pole to a surprisingly balmy 27°C (80°F) at the equator on a summer day. These values are generally much lower than would occur on Earth if our planet orbited the Sun at the distance of Mars, due to the relatively feeble greenhouse effect of the thin martian atmosphere.
One martian year equals just under two Earth years because Mars takes 687 days to complete an orbit.
When Mars is opposite the Sun in our sky it is said to be in opposition. This is also when Mars and Earth are closest together and therefore a good time for making observations. Before the age of space exploration, much of our knowledge about Mars came from studies carried out at these favorable times.
In our next blog we shall learn about "Season On Mars"

Hi, I'm trying to draw the orbits of the inner planets but haven't been able to find the spatial relationship of the aphelion between the orbits. I guess there is no straight line between the sun and the aphelion of all the planets orbits, so, how to figure that out? Greetings
