To answer the question, we need to determine which planet has the highest average surface temperature.
Looking at the table, we can see that the average surface temperatures are given in degrees Celsius (ºC). The planet with the highest average surface temperature will have the highest value in this column.
Comparing the values:
- Venus: 462 ºC
- Earth: 14 ºC
- Mars: -62 ºC
- Jupiter: -145 ºC
- Saturn: -140 ºC
- Neptune: -214 ºC
By comparing the values, we can see that Venus has the highest average surface temperature of 462 ºC. Therefore, Venus has the highest average surface temperature among the listed planets in the table.
To find the answer, compare the values in the "Average Surface Temperature (ºC)" column and identify the planet with the highest value.
