Question

Draw a diagram showing the eight planets of the solar system in their orbits around the sun. Also prepare a table mentioning the length of their days and years.

Answer 1

Planet	Length of day	Length of year
Mercury	$59$ days	$88$ days
Venus	$243$ days	$255$ days
Earth	$1$ day ($=24$ hours)	$1$ year($=365$ days)
Mars	$1$ day($=$ about $24$ hours)	$687$ days
Jupiter	$9.93$ hours	$11.92$ years
Saturn	$10.67$ hours	$29.42$ years
Uranus	$17.23$ hours	$84$ years
Neptune	$16.12$ hours	$164$ years

Remark: $1$ day refers to $1$ Earth day; $1$ year refers to $1$ Earth year. For example the table tells that $1$ Jupiter year is as long as $11.92$ Earth years, and that $1$ Mars day is nearly as much as $1$ Earth day.
