Mars's equatorial Diameter
Mars is a very big planet with an Equatorial diameter of 6,920km(4,220miles).The equatorial diameter is the measurement around the equator.
Mars has a polar diameter of 6,752km(4,196miles).The polar diameter is the measurement from pole to pole(north pole to south pole)
Mars's mass
Mars has a mass of 639e21kg(0.107 earth mass).the E in 639e stands for earth mass.so it would take 639 earths and 21 kilograms to match mars mass.
Mars's surface gravity
Mars has a surface gravity of 3.726527 m/s2.m/s2 stands for meters per second squared.so on mars the gravity pulls down at a speed of 3.726527 square meters per second.mars has 38 percent of the surface gravity of earth.
The atmosphere on mars is made of 96.0% of co2(carbon dioxide),2.1% of AR(argon),1.9% of N(Nitrogen),0.145% of o(oxygen), and 0.0557% of Co(Carbon monoxide).

the gas argon(stated above) is the only noble gas in Mars's atmosphere and all the other gases are nonmetals.
Probes visited
42 probes have visited mars, 20 have failed and the other 22 have given us important information about mars,15 of which were successful flybys.every 26 months there is an opportunity to send a probe/satelite to mars.it takes 6 months or more to reach mars where as Many probes failed and in 2012 the success rate WAS only 47%.
Hello my name is dhruv.I will be talking about the planet mars(also addressed as the red planet)which i the 4th planet from the sun and is the 2nd smallest inner planet.

hope you enjoy!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Fun fact:

did you know?
my name(dhruv) actually means Polaris star
it takes 24 hrs 39 min and 35 seconds
for mars to make a full round on its axis.An axis is an imaginary line that goes through a planet from pole to pole.
Mars's rotational period
mars's orbital period
Mars rotates around the sun
in 687 days.thats 322 more days than earths orbital period!!
mars's temperature
Mars has a temperature of 80
degrees F(-60 degrees c).In winter near the poles the temperature can reach -195 degrees f(-125 degrees c).
the summer near the equator can reach temperatures of 70 degrees f(20 degrees c),but at night the temperature can reach -100 degrees f(-73 degrees c).frost forms on rocks at night but the frost melts and turns into vapor in the morning

fun fact:

did you know?
we are moving through space at the speed 530 km/s!!
mars's moons
mars has 2 moons-Deimos
and Phobos-which are believed to be 2 big asteroids pulled into orbit.phobos has a crater 10 km(6 miles)wide.the crater's name is Stickney.

interesting facts
1.the egyptians were the first people to find and name mars.
2.mars's red color is actually iron oxide(rust).
3.Mars's two sides look different from each other.this gives it a 2 face look.the north is flat while the south is all rocky.
4.it snows co2(carbon dioxide)on mars.the snowflakes are the size of a blood cell!!
5.any rover that earth sends to mars never returns!!
video time!!!!!!
1.what is the only noble gas in mars's atmosphere?
2.what gives mars its red color?
3.what does the e stand for in 639e29kg?
4.what does m/s2 stand for?
5.who found and named mars first?
6.wat evaporates on mars in the morning?

mars has more n(nitrogen) than co2(carbon dioxide)
in its atmosphere.
