In the 1990(exact)s, they worked out one Venusian day - the time for the planet to spin round once - lasted 243.018 (exact)Earth days.

But now, the European Space Agency's Venus Express orbiter shows Venus' spin is getting even slower and a day on Venus is now six and a half(exact) minutes longer.

Scientists aren't sure why.

One cause could be Venus' thick atmosphere and high winds pushing against the planet's spin.

The news is important for future missions to the planet. Scientists use this data to plan missions to the planet and choose the best spot to land a rover.

The new speed means some features on Venus will be 20 kilometres(rounded up/down) away from they were expected to be.

sorry 1990 is approximated

Delete243.018 is exact

DeleteNumbers which are approximated are 1990's and 20 km away.

ReplyDeleteNumbers which are exact are 6 and a half minutes,243.018 days,

1) the 1990s approximation. show the time period not the exact year

ReplyDelete2) the venus day, 243.018 earth days. not approximate

3) 20 km away. approximated

1) In the 1990s- Rounded off

ReplyDelete2)243.018 Earth days.- Exact

3)Six and a half minutes- Exact

4)20 kilometres- Rounded off

Approximate value : 1990, 20km

ReplyDeleteExact value : 6.5 mins, 243.018

1990's ,one venusion day ,20 kilometers

ReplyDeleteall rounded off

ReplyDelete1)In the 1990s,= approx.

ReplyDelete2) lasted 243.018 Earth days = approx.

3)six and a half minutes longer = exact
