How far is Deimos from the sun in AUs?

Hint: Deimos is one of the two outermost natural satellites of the mars and the other one is Phobos.it is the moon of the mars.now as to measure distance between sun and the mars first we have to check the distance between mars and the Deimos and then after we can discover distance between sun and the Deimos.

Complete answer:
Deimos is one of the two outermost natural satellites of the mars and the other one is Phobos.
We can say it is the moon of the mars.
Now as to know the distance from the sun of the Deimos we need to know the distance between the mars and the Deimos.
Now the distance between Mars and the Deimos is 0.0001565AU.
Now if we add this distance in distance between sun and mars then we can get the total distance of sun and the Deimos.
Now the average distance between sun and mars is 1.524AU.
So the distance between sun and Deimos is,
$\begin{align}
  & \Rightarrow d=1.524+0.0001565 \\
 & \therefore d=1.5241565AU \\
\end{align}$
The distance is maximum distance between sun and Deimos (natural satellite of mars)
The full form of the unit AU is an astronomical unit.
One astronomical unit is the approach means the distance between the earth and the sun which is $150\times {{10}^{6}}km$ or 8 light minutes.

Note:
As an approach to solve this question first we discover the distance between deimos and mars which is 0.0001565AU.and then we add this distance in the distance between mars and sun which eventually gives us maximum distance between sun and the deimos. and that distance is 1.5241565 AU.
